        Found by Paul Messmer, see
        http://lists.gnu.org/archive/html/freetype-devel/2010-02/msg00003.html

2010-02-10  Ken Sharp  <ken.sharp@artifex.com>

        Really fix Savannah bug #28678 (part 2).

        Since we consider `sbw' for the horizontal direction only, we still have
        to synthesize vertical metrics if the user wants to use the vertical
        writing direction.

        * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
        (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
        Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
        set.

2010-02-10  Ken Sharp  <ken.sharp@artifex.com>

        Really fix Savannah bug #28678 (part 1).

        After long discussion, we now consider the character width vector
        (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
        direction only.  For example, if you are using the horizontal
        writing direction, you get the horizontal and vertical components of
        the advance width for this direction.  Note that OpenType and CFF fonts
        don't have such a vertical component; instead, the GPOS table can be
        used to generate two-dimensional advance widths (but this isn't
        handled by FreeType).

        * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
        `advance_v' field to hold the vertical component of the advance
        value.

        * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
        (cff_slot_load), src/type1/t1gload.c
        (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
        (cid_load_glyph): Use it.

2010-02-08  Werner Lemberg  <wl@gnu.org>

        * devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define.

2010-02-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Prevent NULL pointer dereference passed to FT_Module_Requester.

        * src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'.
        * src/psnames/psmodule.c (psnames_get_interface): Ditto.

        * src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'.
        * src/truetype/ttdriver.c (tt_get_interface): Ditto.

2010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Fix memory leaks in previous patch.

        * src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings
        allocated for face->root.family_name and style_name.

2010-01-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        New parameters for FT_Open_Face() to ignore preferred family names.

        Preferred family names should be used for legacy systems that
        can hold only a few faces (<= 4) for a family name. Suggested by
        Andreas Heinrich.
        http://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html

        * include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
        FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define.

        * src/sfnt/sfobjs.h (sfnt_load_face): Check the arguments and
        ignore preferred family and subfamily names if requested.

2010-01-27  Ken Sharp  <ken.sharp@artifex.com>

        Fix Savannah bug #28678.

        * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
        (cid_load_glyph): Handle vertical metrics correctly.

        * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle
        vertical metrics correctly.
        (T1_Load_Glyph): Don't synthesize vertical metrics.

2010-01-14  Werner Lemberg  <wl@gnu.org>

        Make FT_Set_Transform work if no renderer is available.

        * src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation
        if no renderer is compiled into the library.

2010-01-14  Werner Lemberg  <wl@gnu.org>

        Fix compilation warning.

        * src/base/ftbase.h: s/LOCAL_DEF/LOCAL/.
        * src/base/ftobjc.s: Include ftbase.h conditionally.

2010-01-11  Kwang Yul Seo  <skyul@company100.net>

        Provide inline assembly code for RVCT compiler.
        This is Savannah patch #7059.

        * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
        FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.

2010-01-08  Ken Sharp  <ken.sharp@artifex.com>

        Fix Savannah bug #28521.

        Issue #28226 involved a work-around for a font which used the
        `setcurrentpoint' operator in an invalid way; this operator is only
        supposed to be used with the result of OtherSubrs, and the font used
        it directly.  The supplied patch removed the block of code which
        checked this usage entirely.

        This turns out to be a Bad Thing.  If `setcurrentpoint' is being
        used correctly it should reset the flex flag in the decoder.  If we
        don't do this then the flag never gets reset and we omit any further
        contours from the glyph (at least until we close the path or
        similar).

        * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
        <op_setcurrentpoint>: Handle `flex_state' correctly.

2010-01-05  Werner Lemberg  <wl@gnu.org>

        Apply reports from clang static analyzer.

        * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c
        (FT_Stroker_ParseOutline), src/base/ftsynth.c
        (FT_GlyphSlot_Embolden): Remove dead code.

        * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
        `offset_i' and `length_i'.

2010-01-05  Ralph Giles  <giles@ghostscript.com>

        Enable the incremental font interface by default.

        Ghostscript requires the incremental font interface for handling
        some Postscript documents.  It is moving to using FreeType as its
        primary renderer; supporting this in the default build makes it
        Ghostscript to be linked against the system FreeType when one is
        available.

        * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
        Uncomment.

2010-01-05  Werner Lemberg  <wl@gnu.org>

        Fix Savannah bug #28395.

        * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c
        (T1_Loada_Glyph): Don't check `num_glyphs' if incremental interface
        is used.

2010-01-05  Ken Sharp  <ken.sharp@artifex.com>

        Make Type 1 `seac' operator work with incremental interface.
        This fixes Savannah bug #28480.

        * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
        if incremental interface is used.

2010-01-04  Ken Sharp  <ken.sharp@artifex.com>

        Make incremental interface work with TrueType fonts.
        This fixes Savannah bug #28478.

        * src/truetype/ttgload.c (load_truetype_glyph): Don't check
        `glyf_offset' if incremental interface is used.

2009-12-31  Lars Abrahamsson  <wonko@opera.com>

        Make compilation with FT_CONFIG_OPTION_PIC work again.

        * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
        Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.

        * src/base/ftinit.c (ft_destroy_default_module_classes,
        ft_create_default_module_classes): Use proper casts (needed for C++
        compilation).

        * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.

2009-12-22  Marc Kleine-Budde  <mkl@pengutronix.de>

        Make freetype-config aware of $SYSROOT.
        This is Savannah patch #7040.

        * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
        appropriate.

2009-12-20  Werner Lemberg  <wl@gnu.org>

        Fix compiler warning.
        Reported by Sean.

        * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
        source files; however, some compilers warn about an unused variable
        declaration.  This is now replaced with a typedef.

2009-12-18  Werner Lemberg  <wl@gnu.org>

        Fix Savannah bug #28320.

        There exist corrupt, subsetted fonts (embedded in PDF files) which
        contain a private dict that ends with an unterminated floating point
        number (no operator following).  We now ignore this error (as
        acrobat does).

        * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
        unterminated floating point numbers.

2009-12-16  Werner Lemberg  <wl@gnu.org>

        Really fix compiler warnings.
        Reported by Sean.

        * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS,
        GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.

2009-12-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
        The linker of Mac OS X 10.6 is sensitive to the architecture.  If
        the architectures are specified explicitly for the C compiler, the
        linker requires the architecture specifications too.

        * builds/unix/configure.raw: Replace `-isysroot' option parser by
        more generic argument parser.

2009-12-15  Werner Lemberg  <wl@gnu.org>

        Fix compiler warnings.
        Reported by Sean.

        * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data
        type.

2009-12-14  Ken Sharp  <ken.sharp@artifex.com>

        Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
        This fixes Savannah bug #28226.

        At least two wild PostScript files of unknown provenance contain
        Type 1 fonts, apparently converted from TrueType fonts in earlier
        PDF versions of the files, which use the `setcurrentpoint' operator
        inappropriately.

        FreeType currently throws an error in this case, but Ghostscript and
        Adobe Distiller both accept the fonts and ignore the problem.  This
        commit #ifdefs out the check so PostScript interpreters using
        FreeType can render these files.

        The specification says `setcurrentpoint' should only be used to set
        the point after a `Subr' call, but these fonts use it to set the
        initial point to (0,0).  Unnecessarily so, as they correctly use an
        `hsbw' operation which implicitly sets the initial point.

        * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
        <op_setcurrentpoint>: Comment out code.

2009-12-14  Bram Tassyns  <bramt@enfocus.be>

        Fix parsing of /CIDFontVersion.
        This fixes Savannah bug #28287.

        * src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in
        t1tables.h) is of type FT_Fixed.

2009-12-14  Werner Lemberg  <wl@gnu.org>

        Trace glyph index in CID module.
        Suggested in Savannah patch #7023.

        * src/cid/cidgload.c (cid_load_glyph): Add tracing message.

2009-12-03  Werner Lemberg  <wl@gnu.org>

        Fix compiler warnings.

        * src/truetype/ttgload.c (tt_get_metrics): Put `Exit' label into the
        proper preprocessor conditional.
        * src/pfr/pfrobjs.c (pfr_slot_load): Pacify gcc.

2009-11-25  John Tytgat  <John.Tytgat@esko.com>

        Better handling of start of `eexec' section.
        This fixes Savannah bug #28090.

        characters before start of `eexec' section.

2009-11-20  Werner Lemberg  <wl@gnu.org>

        [cache] Fix Savannah bug #27441, clean up Redhat bugzilla #513582.
        Tricky casts in FTC_{CACHE,GCACHE,MRULIST}_LOOKUP_CMP() are removed.
        Now these functions should be called with FTC_Node or FTC_MruNode
        variable, and the caller should cast them to appropriate pointers to
        concrete data.  These tricky casts can GCC-4.4 optimizer (-O2)
        confused and the crashing binaries are generated.

        * src/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Drop tricky cast.
        Now the 4th argument `node' of this function should be typed as
        FTC_MruNode.

        * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): For inline
        implementation, new temporal variable FTC_MruNode `_mrunode' to take
        the pointer from FTC_MRULIST_LOOKUP_CMP().  For non-inline
        implementation, tricky cast is dropped.

        * src/cache/ftcmanag.c (FTC_SIZE_NODE): New macro casting
        to FTC_SizeNode.
        (FTC_Manager_LookupSize): Replace FTC_SizeNode `node' by FTC_MruNode
        `mrunode', and FTC_SIZE_NODE() is inserted.
        (FTC_FACE_NODE): New macro casting to FTC_FaceNode.
        (FTC_Manager_LookupFace) Replace FTC_FaceNode `node' by FTC_MruNode
        `mrunode', and FTC_FACE_NODE() is inserted.

        * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Change the type of
        `node' from FTC_INode to FTC_Node.  Extra casting macro FTC_NODE()
        is dropped.
        (FTC_ImageCache_LookupScaler): Ditto.
        (FTC_SBitCache_Lookup): Change the type of `node' from FTC_SNode to
        FTC_Node.  Extra casting macro FTC_NODE() is dropped.  FTC_SNODE()
        is inserted.

        [BDF] Modify hash API to take size_t value instead of void *.

        The hash API in BDF driver is designed to be generic, it takes
        void * typed data.  But BDF driver always gives an unsigned long
        integer (the index to a property).  To reduce non-essential
        casts from unsigned long to void* and from void* to unsigned
        long, the hash API is changed to take size_t integer.
        The issue of incompatible cast between unsigned long and void*
        on LLP64 platform is reported by NightStrike from MinGW-Win64
        project.  See
        http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

        * src/bdf/bdf.h: The type of hashnode->data is changed from

        void* data.
        (bdf_create_property): Get the name length of new property by
        size_t variable, with a cut-off at FT_ULONG_MAX.
        (_bdf_set_default_spacing): Get the name length of the face by
        size_t variable, with a cut-off at 256.
        (bdf_get_property): Get the property id by size_t variable to
        reduce the casts between 32-bit prop ID & hashnode->data during
        simple copying.
        (_bdf_add_property): Ditto.
        (_bdf_parse_start): Calculate the index to the property array
        by size_t variable.
        (bdf_get_font_property): Drop a cast to unsigned long.

        Improve vertical metrics calculation (Savannah bug #27364).

        The calculation of `vertBearingX' is not defined in the OTF font
        spec so FreeType does a `best effort' attempt.  However, this value
        is defined in the PDF and PostScript specs, and that algorithm is
        better than the one FreeType currently uses:

          FreeType: Use the middle of the bounding box as the X coordinate
                    of the vertical origin.

          Adobe PDF spec: Use the middle of the horizontal advance vector as
                          the X coordinate of the vertical origin.

        FreeType's algorithm goes wrong if you have a really small glyph
        (like the full-width, circle-like dot at the end of the sentence, as
        used in CJK scripts) with large bearings.  With the FreeType
        algorithm this dot gets centered on the baseline; with the PDF
        algorithm it gets the correct location (in the top right).  Note
        that this is a serious issue, it's like printing the dot at the end
        of a Roman sentence at the center of the textline instead of on the
        baseline like it should. So i believe the PDF spec's algorithm
        should be used in FreeType as well.

        The `vertBearingY' value for such small glyphs is also very strange
        if no `vmtx' information is present, since the height of the bbox is
        not representable for the height of the glyph visually (the
        whitespace up to the baseline is part of the glyph).  The fix also
        includes some code for a better estimate of `vertBearingY'.

        * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
        is now calculated as described by the Adobe PDF Spec.  Estimate for
        `vertBearingY' now works better for small glyphs completely above or
        below the baseline into account.

        * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
        calculated as described by the Adobe PDF Spec.  Vertical metrics
        information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
        was not defined.

        * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
        now calculated as described by the Adobe PDF Spec.

        truetype: Extend TrueType GX packed deltas to FT_Offset.

        * src/truetype/ttgxvar.c (ft_var_readpackeddeltas):
        The type of 2nd argument `delta_cnt' is changed from
        FT_Int to FT_Offset, because its source can be cvt
        table size calculated from stream position.

        truetype: Truncate the deltas of composite glyph at 16-bit values.

        * src/truetype/ttgload.c (load_truetype_glyph):
        Insert cast from FT_Long (deltas[i].{x,y}) to
        FT_Int16 in the summation of deltas[] for composite
        glyphs.  Because deltas[i] is typed as FT_Pos,
        its component x, y are typed as FT_Long, but
        their sources are always FT_Int16 when they are
        loaded by ft_var_readpackeddeltas().  However,
        the limitation about the summed deltas is unclear.

        tt_cmap14_get_nondef_chars, tt_cmap14_variant_chars)
        Insert casts when FT_UInt32 variable is loaded by
        TT_NEXT_{UINT24|ULONG}.  Because most of them are
        compared with FT_UInt32 values in public API, replacing
        FT_UFast is not recommended.

2009-07-31  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        sfnt: Cast a character code to FT_UInt32 for LP64 system.

        * src/sfnt/ttcmap.c (tt_cmap4_init, tt_cmap4_next):

        sfnt: Extend TT_BDF->strings_size to FT_ULong for huge BDF.

        * include/freetype/internal/tttypes.h: The type
        of TT_BDF->string_size is extended from FT_UInt32
        to FT_ULong, because BDF specification does not
        restrict the length of string.
        * src/sfnt/ttbdf.c: The scratch variable `strings'

        afm_parse_kern_pairs, afm_parse_kern_data,
        afm_parser_skip_section, afm_parser_parse):
        The length of key is handled by FT_Offset,
        instead of FT_UInt.  Although the length of
        PostScript strings or name object is 16-bit,
        AFM_STREAM_KEY_LEN() calculates the length
        from the pointer difference.

        * src/psaux/afmparse.h (afm_parser_next_key):

        * src/pcf/pcfread.c (pcf_interpret_style): The types
        of nn, len, lengths[4] are changed to size_t, because
        they are loaded by (or compared with) ft_strlen().

        * src/pcf/pcfutil.c (BitOrderInvert, TwoByteSwap,
        FourByteSwap): The type of the 2nd argument `nbytes'
        is changed to size_t, for similarity with ANSI C
        string functions.

        * src/pcf/pcfdrivr.c (PCF_Glyph_Load): The type of
        `bytes' is changed to FT_Offset, because it is passed
        to FT_ALLOC(), via ft_glyphslot_alloc_bitmap().  At
        least, using unsigned type is better.

2009-07-31  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/cache/ftcbasic.c (FTC_ImageCache_Lookup,
        FTC_SBitCache_Lookup): The type of FTC_ImageType->width
        is FT_Int, so the cast to unsigned larger type FT_ULong
        is introduced for the comparisons with 0x10000L for
        LP64 platform.

        smooth: Fix some data types mismatching with their sources.

        * src/smooth/ftgrays.c: The type of `TCoord' is
        matched to `TPos', because they are mixed in
        gray_set_cell().  The type of TCell->x is extended
        to `TPos', because gray_find_cell() sets it by
        TWorker.ex.  The type of TCell->cover is extended
        to `TCoord', because gray_render_scanline() adds
        TCoord value to it.  The type of TWork.cover is matched
        with TCell->cover.  The types of
        TWork.{max_cells,num_cells} are changed to FT_PtrDist,
        because they are calculated from the memory addresses.
        The type of TWork.ycount is changed to TPos, because
        it is calculated from TPos variables.
        (gray_find_cell): The type of `x' is matched with
        its initial value ras.ex.
        (gray_render_scanline): The types of `mod', `lift'
        and `rem' are changed to TCoord, because their values
        are set with explicit casts to TCoord.  When ras.area
        is updated by the differential values including
        `delta', they are explicitly cast to TArea, because
        the type of `delta' is not TArea but TCoord.
        (gray_render_line): The type of `mod' is extended
        from int to TCoord, because (TCoord)dy is added to mod.
        (gray_hline): The argument `acount' is extended to
        TCoord, to match with the parameters in the callers.

        Insert explicit cast to compare
        FT_Long AF_FaceGlobalsRec.glyph_count versus

        to scan glyph index upto AF_FaceGlobalsRec.glyph_count.
        (af_face_globals_get_metrics): The type of `script_max'
        is changed to cover size_t value.  Insert explicit cast

        * src/autofit/aflatin.c (af_latin_hint_edges):
        Ditto.

        * src/autofit/aftypes.h: In AF_ScriptClassRec,

        be counted by FT_Offset variable instead of FT_UInt.

        * src/autofit/afhints.c
        (af_glyph_hints_align_strong_points): The cursors
        for the edges `min', `max', `mid' in the memory

        * src/base/ftcalc.c (ft_corner_orientation): Change
        the internal calculation from FT_Int to FT_Long, to
        avoid an overflow on 16-bit platforms.  The caller of
        this function should use only the sign of result,
        so the cast to FT_Int is acceptable.
        
        * src/base/ftsynth.c: Introduce a tracer for synth module.
        (FT_GlyphSlot_Embolden): Check invalid strength causing
        integer overflow on 16-bit platform.
        
        * src/bdf/bdfdrivr.c (BDF_Face_Init): The glyph index
        in FT2 API is typed as FT_UInt, although BDF driver
        can handle unsigned long glyph index internally.  To
        avoid integer overflow on 16-bit platform, too large
        glyph index should be excluded.
        (BDF_Glyph_Load): The glyph pitch in FT2 is typed as
        FT_UInt, although BDF driver can handle unsigned long
        glyph pitch internally.  To avoid integer overflow on

        returned.
        
        * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): The glyph
        pitch in FT2 is typed as FT_UInt, although PFR font
        format can include huge bitmap glyph with 24-bit pitch
        (however, a glyph spends 16.7 pixel, it's not realistic).
        To avoid integer overflow on 16-bit platform, huge
        bitmap glyph should be excluded.
        
        * src/smooth/ftgrays.c (gray_hline): As FT_Span.x is
        truncated to fit its type (16-bit short), FT_Span.y
        should be truncated to fit its type (FT_Int).
        
        * src/cff/cffdrivr.c (cff_get_ros): CFF specification
        defines the supplement in ROS as a real number.
        Truncate it to fit public FT2 API.

        Use 16.16 format while parsing Type 1 charstrings.
        This fixes Savannah bug #26867.

        Previously, only integers have been used which can lead to serious
        rounding errors.

        However, fractional values are only used internally; after the
        charstrings (of either Type 1 or 2) have been processed, the
        resulting coordinates get rounded to integers currently -- before
        applying scaling.  This should be fixed; at the same time a new load
        flag should be introduced, to be used in combination with
        FT_LOAD_NO_SCALE, which indicates that font units are returned in
        16.16 format.  Similarly, the incremental interface should be
        extended to allow fractional values for metrics.

2009-06-18  Werner Lemberg  <wl@gnu.org>

        Fix B/W rasterization of subglyphs with different drop-out modes.

        Normally, the SCANMODE instruction (if present) to set the drop-out
        mode in a TrueType font is located in the `prep' table only and thus
        valid for all glyphs.  However, there are fonts like `pala.ttf'
        which additionally contain this instruction in the hinting code of
        some glyphs (but not all).  As a result it can happen that a
        composite glyph needs multiple drop-out modes for its subglyphs
        since the rendering state gets reset for each subglyph.

        FreeType collects the hinted outlines from all subglyphs, then it
        sends the data to the rasterizer.  It also sends the drop-out mode
        -- after hinting has been applied -- and here is the error: It sends
        the drop-out mode of the last subglyph only; drop-out modes of all
        other subglyphs are lost.

        This patch fixes the problem; it adds a second, alternative
        mechanism to pass the drop-out mode: For each contour, the
        rasterizer now checks the first `tags' array element.  If bit 2 is
        set, bits 5-7 contain the contour's drop-out mode, overriding the
        global drop-out mode.

        * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.

        * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
        `tags[0]'.

        * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
        Use bits 3-5 instead of 0-2.
        (New_Profile): Set the drop-out mode in the profile's `flags' field.
        (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
        necessary.
        (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
        Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
        mode.

2009-06-16  Werner Lemberg  <wl@gnu.org>

        Improve scan conversion rules 4 and 6.

        Two new constraints are introduced to better identify a `stub' -- a
        concept which is only vaguely described in the OpenType
        specification.  The old code was too rigorous and suppressed more
        pixel than it should.

          . The intersection of the two profiles with the scanline is less
            than a half pixel.  Code related to this was already present in
            the sources but has been commented out.

          . The endpoint of the original contour forming a profile has a
            distance (`overshoot') less than half a pixel to the scanline.

        Note that the two additional conditions fix almost all differences
        to the Windows rasterizer, but some problematic cases remain.

        * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
        macros for the `flags' field in the `TProfile' structure.

        * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.

2009-03-09  Alexey Kryukov  <anagnost@yandex.ru>

        Fix handling of EBDT formats 8 and 9 (part 2).

        This patch fixes the following problems in ttsbit0.c:

        . Bitmaps for compound glyphs were never allocated.

        . `SBitDecoder' refused to load metrics if some other metrics have
          already been loaded.  This condition certainly makes no sense for
          recursive calls, so I've just disabled it.  Another possibility
          would be resetting `decoder->metrics_loaded' to false before
          loading each composite component.  However, we must restore the
          original metrics after finishing the recursion; otherwise we can
          get a misaligned glyph.

        . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
          causing some glyph components to be shifted too far to the right
          (especially noticeable for small sizes).

        Note that support for grayscale bitmaps (not necessarily compound) is
        completely broken in ttsbit0.c.

        * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
        (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
        of `h == height'.
        (tt_sbit_decoder_load_compound): Reset metrics after loading
        components.
        Allocate bitmap.

2009-03-03  David Turner  <david@freetype.org>

        Remove ABI-breaking field in public PS_InfoFontRec definition.

        Instead, we define a new internal PS_FontExtraRec structure to
        hold the additional field, then place it in various internal
        positions of the corresponding FT_Face derived objects.

        `fs_type' field from the public structure.

2009-03-02  Alexey Kryukov  <anagnost@yandex.ru>

        Fix handling of EBDT formats 8 and 9.

        The main cycle in `blit_sbit' makes too many iterations: it actually
        needs the count of lines in the source bitmap rather than in the
        target image.

        * src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]:
        Add parameter `source_height' and use it for main loop.
        (Load_SBit_Single) [FT_CONFIG_OPTION_OLD_INTERNALS]: Updated.

        * src/sfnt/sfobjs.c (sfnt_load_face): Test for bitmap strikes before
        setting metrics and bbox values.  This ensures that the check for a
        font with neither a `glyf' table nor bitmap strikes can be performed
        early enough to set metrics and bbox values too.

        FT_USE_MODULE declares things as:

          extern const FT_Module_Class

        (or similar for C++).  However, the actual types of the variables
        being declared are often different, e.g., FT_Driver_ClassRec or
        FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

        This works with most C compilers (since those structs begin with an
        FT_Module_Class struct), but technically it's undefined behavior.

        To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
        paragraph 2:

          All declarations that refer to the same object or function shall
          have compatible type; otherwise, the behavior is undefined.

        (And they are not compatible types.)

        Most C compilers don't reject (or even detect!) code which has this
        issue, but the GCC LTO development branch compiler does.  (It
        outputs the types of the objects while generating .o files, along
        with a bunch of other information, then compares them when doing the
        final link-time code generation pass.)

2008-12-10  Werner Lemberg  <wl@gnu.org>

        Generalize the concept of `tricky' fonts by introducing
        FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
        engine is necessary for correct rendering.

        At the same time, slightly modify the behaviour of tricky fonts:
        FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
        of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
        FT_LOAD_NO_AUTOHINT must be used.

        Finally, tricky TrueType fonts always use the bytecode interpreter
        even if the patented code is used.

        * include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
        New macros.

        fonts.

2008-10-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/sfnt/sfobjs.c (sfnt_open_font): Allow `typ1' version tag in
        the beginning of sfnt container.
        * src/sfnt/ttload.c (check_table_dir): Return
        `SFNT_Err_Table_Missing' when sfnt table directory structure is
        correct but essential tables for TrueType fonts (`head', `bhed' or
        `SING') are missing.  Other errors are returned by
        SFNT_Err_Unknown_File_Format.

        * src/base/ftobjs.c (FT_Open_Face): When TrueType driver returns
        `FT_Err_Table_Missing', try `open_face_PS_from_sfnt_stream'.  It is
        enabled only when old mac font support is configured.

2008-10-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * include/freetype/tttags.h (TTAG_CID, TTAG_FOND, TTAG_LWFN,
        TTAG_POST, TTAG_sfnt, TTAG_TYP1, TTAG_typ1): New tags to simplify
        the repeated calculations of these values in ftobjs.c and ftmac.c.
        * src/base/ftobjs.c: Replace all FT_MAKE_TAG by new tags.
        * src/base/ftmac.c: Ditto.

2008-10-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Replaced by...
        (ft_lookup_PS_in_sfnt_stream): This.
        (open_face_PS_from_sfnt_stream): New function.  It checks whether
        the stream is sfnt-wrapped Type1 PS font or sfnt-wrapped CID-keyed
        font, then try to open a face for given face_index.
        (Mac_Read_sfnt_Resource): Replace the combination of
        `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' by
        `open_face_PS_from_sfnt_stream'.
        * src/base/ftmac.c (FT_New_Face_From_SFNT): Ditto.
        * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
        * src/base/ftbase.h: Remove `ft_lookup_PS_in_sfnt' and add
        `open_face_PS_from_sfnt_stream'.

2008-10-03  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Set *is_sfnt_cid to
        FALSE if neither `CID ' nor `TYP1' is found in the sfnt container.

2008-10-03  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * include/freetype/config/ftconfig.h: Define FT_MACINTOSH when SC or
        MrC compiler of MPW is used.  These compilers do not define the
        macro __APPLE__ by themselves.
        * builds/unix/ftconfig.in: Ditto.
        * builds/vms/ftconfig.h: Ditto.
        * src/base/ftbase.c: Use FT_MACINTOSH instead of __APPLE__, to
        include ftmac.c if FreeType 2 is built by MPW.
        * src/base/ftobjs.c: Use FT_MACINTOSH instead of __APPLE__, to
        enable shared functions for ftmac.c if FreeType 2 is built by MPW.

        * builds/mac/ftmac.c: Include ftbase.h.
        (memory_stream_close): Removed.
        (new_memory_stream): Ditto.
        (open_face_from_buffer): Removed.  Use the implementation in
        ftobjs.c.
        (ft_lookup_PS_in_sfnt): Ditto.

        * builds/mac/FreeType.m68k_far.make.txt: Build ftmac.c as an
        included part of ftbase.c, to share the functions in ftobjs.c.  The
        rule compiling ftmac.c separately is removed and the rule copying
        ftbase.c from src/base/ftbase.c to builds/mac/ftbase.c is added.
        * builds/mac/FreeType.m68k_cfm.make.txt: Ditto.
        * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
        * builds/mac/FreeType.ppc_carbon.make.txt: Ditto.

2008-10-02  Bram Tassyns  <bramt@enfocus.be>

        * src/cff/cffgload.c (cff_slot_load): Map CID 0 to GID 0.  This
        fixes Savannah bug #24430.

2008-10-02  Werner Lemberg  <wl@gnu.org>

        * builds/freetype.mk (BASE_H): Rename to...
        (INTERNAL_H): This.
        (FREETYPE_H): Updated.
        * src/base/rules.mk: (BASE_OBJ_S, OBJ_DIR/%.$O): Add BASE_H.
        * src/bdf/rules.mk (BDF_DRV_H): Add bdferror.h.
        * src/cache/rules.mk (CACHE_DRV_H): Add ftccache.h and ftcsbits.h.
        * src/pcf/rules.mk (PCF_DRV_H): Add pcfread.h.

        * src/type42/rules.mk (T42_DRV_H): Add t42types.h.

2008-10-02  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftbase.h: New file to declare the private utility
        functions shared by the sources of base modules.  Currently,
        `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
        share between ftobjs.c and ftmac.c.

        * src/base/rule.mk: Add ftbase.h.

        * src/base/ftobjs.c: Include ftbase.h.
        (memory_stream_close): Build on any platform when old MacOS font
        support is enabled.
        (new_memory_stream): Ditto.
        (open_face_from_buffer): Build on any platform when old MacOS font
        support is enabled.  The counting of the face in a font file is
        slightly different between Carbon-dependent parser and Carbon-free
        parser.  They are merged with the platform-specific conditional.
        (ft_lookup_PS_in_sfnt): Ditto.

        * src/base/ftmac.c: Include ftbase.h.
        (memory_stream_close): Removed.
        (new_memory_stream): Ditto.
        (open_face_from_buffer): Removed.  Use the implementation in
        ftobjs.c.
        (ft_lookup_PS_in_sfnt): Ditto.

2008-10-02  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (sfnt_load_face): `psnames_error' is only needed
        if TT_CONFIG_OPTION_POSTSCRIPT_NAMES is defined.

2008-10-01  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c

        src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c
        (cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done),
        src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0.
        Reported by Graham Asher.

2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/rules.mk: Add conditional source to BASE_SRC, for `make
        multi' on Mac OS X.  If the macro $(ftmac_c) is defined,
        $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC.  In a normal build, the
        lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
        ftmac.c.
        * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
        * builds/unix/configure.raw: Add procedure to set up appropriate
        value of $(ftmac_c) with the consideration of the availability of
        Carbon framework.

2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/Jamfile: Add target for multi build by jam on Mac OS X.
        * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this
        function for MPW building.  It is synchronized the condition to
        include ftmac.c source into ftbase.c.

2008-09-22  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
        cff_decoder_parse_charstrings): Handle (invalid)
        `callothersubr' and `pop' instructions.

2008-09-22  John Tytgat  <John.Tytgat@esko.com>

        Fix Savannah bug #24307.

        * include/freetype/internal/t1types.h (CID_FaceRec),
        src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.

2008-09-21  Werner Lemberg  <wl@gnu.org>

        * src/smooth/ftgrays.c (gray_raster_render): Don't dereference
        `target_map' if FT_RASTER_FLAG_DIRECT is set.  Problem reported by
        Stephan T. Lavavej <stl@nuwen.net>.

2008-09-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/otvalid/Jamfile: Add missing target `otvmath' for multi build
        by jam.
        * src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
        jam.

2008-09-20  Werner Lemberg  <wl@gnu.org>

        * src/smooth/ftgrays.c (gray_find_cell): Fix threshold.  The values
        passed to this function are already `normalized'.  Problem reported
        by Stephan T. Lavavej <stl@nuwen.net>.

        * docs/CHANGES: Document it.

2008-09-20  Werner Lemberg  <wl@gnu.org>

        * src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
        (FT_Outline_Decompose): Decorate with tracing messages.

        * src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
        FT_DEBUG_LEVEL_TRACE.
        [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
        stdarg.h.

        (FT_TRACE) [_STANDALONE_]: Remove.
        (FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
        (FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.
        (FT_ERROR) [_STANDALONE_]: Updated.

        (gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
        Use FT_TRACE7.
        (gray_dump_cells): Make it `static void'.
        (gray_convert_glyph): Use FT_TRACE7.

        (FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
        ftoutln.c.

        * src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
        FT_ERROR_BASE.

        * docs/formats.txt: Updated.

2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c: Import sfnt-wrapped Type1 and sfnt-wrapped
        CID-keyed font support.
        * builds/mac/ftmac.c: Ditto.

2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
        sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
        `open_face_from_buffer' frees the passed buffer if it cannot open a
        face from the buffer, so the caller must not free it.

2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
        for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
        (ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '
        table in sfnt table directory.  It is used before loading TrueType
        font driver.

        * docs/CHANGES: Add note about the current status of sfnt-wrapped
        Type1 and sfnt-wrapped CID-keyed font support.

2008-09-18  Werner Lemberg  <wl@gnu.org>

        * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
        orthogonality (ft_free and ft_sfree could belong to different memory
        pools).  This fixes Savannah bug #24297.

2008-09-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
        in ttags.h instead of numerical value 0x4F54544FL.

2008-09-16  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffgload.h, src/cff/cffgload.c
        (cff_decoder_set_width_only): Eliminate function call.

2008-09-15  George Williams  <gww@silcom.com>

        Fix Savannah bug #24179, reported by Bram Tassyns.

        * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
        of default values.

2008-09-15  Werner Lemberg  <wl@gnu.org>

        * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
        and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
        prevent unconditional definition.  This fixes Savannah bug #24241.

        * src/psnames/pstables.h: Regenerated.

2008-09-13  Werner Lemberg  <wl@gnu.org>

        * autogen.sh, builds/unix/configure.raw,
        include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
        beautifying.

        * include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
        include/freetype/ftlcdfil.h: Protect against FreeType 1.
        Some other minor fixes.

        * devel/ftoption.h: Synchronize with
        include/freetype/config/ftoption.h.

2008-09-11  Werner Lemberg  <wl@gnu.org>

        * src/base/ftbase.c: Include ftadvanc.c.

2008-09-11  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/ftconfig.in: Duplicate the cpp computation of
        FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
        (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp
        computation is disabled and the statically configured sizes are
        used.  This fixes Savannah bug #21250.

        * builds/unix/configure.raw: Add the checks to compare the cpp
        computation results of the bit length of int and long versus the
        sizes detected by running `configure'.  If the results are
        different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
        results.
        New option --{enable|disable}-biarch-config is added to define or
        undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.

2008-09-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
        ApplicationService framework is missing.  Although this value is not
        used in building of FreeType2, it is written in `freetype2.pc' and
        `freetype-config'.

2008-09-01  david turner  <david@freetype.org>

        * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
        index to mean `use default cached FT_Face's charmap'.  This fixes
        Savannah bug #22625.
        * include/freetype/ftcache.h: Document it.


        Make FT_MulFix an inlined function.  This is done to speed up
        FreeType a little (on x86 3% when loading+hinting, 10% when
        rendering, ARM savings are more important though).  Disable this by
        undefining FT_CONFIG_OPTION_INLINE_MULFIX.

        Use of assembler code can now be controlled with
        FT_CONFIG_OPTION_NO_ASSEMBLER.

        * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
        [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler
        implementation.
        [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler
        implementation taken from `ftcalc.c'.
        [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
        which is defined to the platform-specific assembler implementation
        of FT_MulFix.
        [FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
        (FT_MULFIX_INLINED): New macro.

        * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
        FT_CONFIG_OPTION_INLINE_MULFIX): New macros.

        * include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.

        * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
        FT_MULFIX_INLINED.


        Add a new header named FT_ADVANCES_H declaring some new APIs to
        extract the advances of one or more glyphs without necessarily
        loading their outlines.  Also provide `fast loaders' for the
        TrueType, Type1, and CFF font drivers (more to come later).

        * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.

        * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
        * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.

        * include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
        `flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
        respectively.

        * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add
        ftadvanc.c.

        * src/cff/cffdrivr.c (cff_get_advances): New function.
        (cff_driver_class): Register it.

        * src/cff/cffgload.c (cff_decoder_set_width_only): New function.
        (cff_decoder_parse_charstrings): Handle `width_only'.
        (cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.

        * src/cff/cffgload.h (cff_decoder): New element `width_only'.
        (cff_decoder_set_width_only): New declaration.

        * src/truetype/ttdriver.c (tt_get_advances): New function.
        (tt_driver_class): Register it.

        * src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
        (TT_Get_HMetrics, TT_Get_VMetrics): This.
        Update callers.
        * src/truetype/ttgload.h: Declare them.

        * src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
        function.
        * src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.


        Add checks for minimum version of the `autotools' stuff.

        * autogen.sh: Implement it.
        (get_major_version, get_minor_version, get_patch_version,
        compare_to_minimum_version, check_tool_version): New auxiliary
        functions.

        * README.CVS: Document it.

2008-08-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
        ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).

2008-08-28  Werner Lemberg  <wl@gnu.org>

        * src/type1/t1load.c (parse_encoding): Protect against infinite
        loop.  This fixes Savannah bug #24150 (where a patch has been posted
        too).

2008-08-23  Werner Lemberg  <wl@gnu.org>

        * src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
        (afm_compare_kern_pairs): Fix comparison.  This fixes Savannah bug
        #24119.

2008-08-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
        even if passed library or arguments are invalid.  This fixes a bug
        that an uninitialized stream is freed when an invalid library handle
        is passed.  Originally proposed by Mike Fabian, 2008/08/18 on
        freetype-devel.
        (FT_Open_Face): Ditto (stream).
        (load_face_in_embedded_rfork): Ditto (stream2).

2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c: Add a fallback to guess the availability of the
        `ResourceIndex' type.  It is used when built without configure
        (e.g., a build with Jam).
        * builds/mac/ftmac.c: Ditto.
        * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
        explicitly, even if `ResourceIndex' is unavailable.

2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: In checking of Mac OS X features,
        all-in-one header file `Carbon.h' is replaced by the minimum
        header file `CoreServices.h', similar to current src/base/ftmac.c.

2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
        sub-header when its code_count is 0.  Many Japanese Dynalab fonts
        include such an empty sub-header (code_count == 0, first_code == 0
        delta == 0, but offset != 0) as the second sub-header in SJIS cmap.

2008-08-04  Werner Lemberg  <wl@gnu.org>

        * src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes
        Savannah bug #23995.

        * src/cid/cidload.c (parse_expansion_factor): New callback function.
        (cid_field_records): Use it for `ExpansionFactor'.
        * src/cod/cidtoken.h: Handle `ForceBold' keyword.
        Don't handle `ExpansionFactor'.

2008-08-04  Bram Tassyns  <bramt@enfocus.be>

        * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
        resulted in incorrect scaling.  This fixes Savannah bug #23973.

2008-08-04  Werner Lemberg  <wl@gnu.org>

        Be more tolerant w.r.t. invalid entries in SFNT table directory.

        * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
        adjust table count.
        Add more trace messages.
        (tt_face_load_font_dir): Updated.

2008-07-30  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
        assume that the first argument on the stack is the bottom-most
        element.  Two reasons:

          o According to people from Adobe it is missing in the Type 2
            specification that pushing of additional, superfluous arguments
            on the stack is prohibited.

          o Acroread in general handles fonts differently, namely by popping
            the number of arguments needed for a particular operand (as a PS
            interpreter would do).  In case of buggy fonts this causes a
            different interpretation which of the elements on the stack are
            superfluous and which not.

        Since there are CFF subfonts (embedded in PDFs) which rely on
        Acroread's behaviour, FreeType now does the same.

2008-07-27  Werner Lemberg  <wl@gnu.org>

        Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This
        fixes Savannah bug #23940.

        * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
        (EXTRA_GLYPH_LIST_SIZE): This.
        Increase by 2.
        (ft_wgl_extra_unicodes): Rename to...
        (ft_extra_glyph_unicodes): This.
        Add two code values.
        (ft_wgl_extra_glyph_names): Rename to...
        (ft_extra_glyph_names): This.
        Add two glyphs.
        (ft_wgl_extra_glyph_name_offsets): Rename to...
        (ft_extra_glyph_name_offsets): This.
        Add two offsets.

        (ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
        (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
        Updated.
        (ps_unicodes_init): Updated.

2008-07-26  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffgload.c (cff_decoder_prepare,
        cff_decoder_parse_charstrings): Improve debug output.

2008-07-22  Martin McBride  <mmcbride@emtex.com>

        * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
        tt_cmap4_char_map_binary): Handle fonts which treat the last segment
        specially.  According to the specification, such fonts would be
        invalid but acroread accepts them.

2008-07-16  Jon Foster  <Jon.Foster@cabot.co.uk>

        * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

        * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
        Fix compiler warning.

2008-07-16  Werner Lemberg  <wl@gnu.org>

        Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.

        * src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
        Invert sids table only if `pure_cff' is set.
        * src/cff/cffload.h: Udpated.

        * src/cff/cffobjs.c (cff_face_init): Updated.
        Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.

        * docs/CHANGES: Updated.

2008-07-09  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
        where num_locations < num_glyphs.  Problem reported by Ding Li.

2008-07-05  Werner Lemberg  <wl@gnu.org>

        Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
        newer.  This fixes Savannah bug #23648.

        * configure: zsh doesn't like ${1+"$@"}.
        Update needed GNU make version.
        * builds/toplevel.mk: Check for `$(eval ...)'.
        * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
        it.

2008-07-04  Werner Lemberg  <wl@gnu.org>

        * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
        pixel, only check for dropouts if neither start nor end point lies
        on a pixel center.  This fixes Savannah bug #23762.

2008-06-29  Werner Lemberg  <wl@gnu.org>

        * Version 2.3.7 released.
        =========================


        Tag sources with `VER-2-3-7'.

        * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
        version number to 2.3.7.

        * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
        builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj,
        builds/win32/visualce/index.html,
        builds/win32/visualce/freetype.dsp,
        builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.

        * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.

        * builds/unix/configure.raw (version_info): Set to 9:18:3.

        * docs/release: Updated.

2008-06-28  Werner Lemberg  <wl@gnu.org>

        * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
        * src/ftcalc.c: Here.  This fixes Savannah bug #23729.

2008-06-27  Werner Lemberg  <wl@gnu.org>

        * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
        Horizontal_Gray_Sweep_Drop): Test for intersections which
        degenerate to a single point can be ignored; this has been confirmed
        by Greg Hitchcock from Microsoft.  (This was commented out code.)

2008-06-26  Werner Lemberg  <wl@gnu.org>

        Improve navigation in API reference.

        * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
        (html_header_6): This.
        (html_header_3, html_header_3i, html_header_4, html_header_5,
        html_header_5t): New strings.
        (toc_footer_start, toc_footer_end): New strings.
        (HtmlFormatter::html_header): Updated.
        (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
        New strings.
        (HtmlFormatter::index_enter): Use `html_index_header'.
        (HtmlFormatter::index_exit): Print `html_footer'.
        (HtmlFormatter::toc_enter): Use `html_toc_header'.
        (HtmlFormatter::toc_exit): Print proper footer.

        Convert ~ to non-breakable space.

        * src/tools/docmaker/tohtml.py (make_html_para): Implement it.
        Update header files accordingly.

2008-06-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
        and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
        bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
        ResourceIndex type definition.  The macro does not inform the type
        availability.
        * src/base/ftmac.c: More parentheses are inserted to clarify the
        conditionals to disable legacy APIs in `10.5 and later' cases.  If
        HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.

2008-06-24  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
        mode.

        * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
        Draw_Sweep): No-dropout mode is value 2, not value 0.
        (Draw_Sweep): Really skip dropout handling for no-dropout mode.

2008-06-24  Werner Lemberg  <wl@gnu.org>

        * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
        if it consists of one point only.  Based on a patch from Savannah
        bug #23683 (from John Tytgat).

2008-06-22  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
        with IS_HINTED.

        * docs/CHANGES: Updated.

2008-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
        but LDFLAGS does not, import it to LDFLAGS.  The option is used to
        specify non-default SDK on Mac OS X (e.g., universal binary SDK for
        Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
        recommends to add the option only to CFLAGS, LDFLAGS should include
        it because libfreetype.la is built with -no-undefined.  This fixes a
        bug reported by Ryan Schmidt in MacPorts,
        http://trac.macports.org/ticket/15331.

2008-06-21  Werner Lemberg  <wl@gnu.org>

        Enable access to the various dropout rules of the B&W rasterizer.
        Pass dropout rules from the TT bytecode interpreter to the
        rasterizer.

        * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
        FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.

        * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
        Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
        OpenType specification.
        Fix mode 4 computation.
        (Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

        * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
        mode to FT_OUTLINE_XXX flags.

        * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

2008-06-19  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffobjs.c (cff_face_init): Compute final
        `dict->units_per_em' value before assigning it to
        `cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
        scaled incorrectly if the font matrix is non-standard.  This fixes
        Savannah bug #23630.

        * docs/CHANGES: Updated.

2008-06-19  Werner Lemberg  <wl@gnu.org>

        * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
        from 2008-06-19.

2008-06-18  Werner Lemberg  <wl@gnu.org>

        * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.
        Reported by Peter Weilbacher <mozilla@weilbacher.org>.

        * docs/CHANGES: Updated.

2008-06-15  George Williams  <gww@silcom.com>

        * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
        `valid->extra2' to 1.  This is undocumented in the OpenType 1.5
        specification.

2008-06-15  Werner Lemberg  <wl@gnu.org>

        * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
        from clobbering.  Patch from Savannah bug report #23556.

        * docs/CHANGES: Document it.

2008-06-10  Werner Lemberg  <wl@gnu.org>

        * autogen.sh: Add option `--install' to libtoolize.

2008-06-10  Werner Lemberg  <wl@gnu.org>

        * Version 2.3.6 released.
        =========================


        Tag sources with `VER-2-3-6'.

        * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
        version number to 2.3.6.

        * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
        builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj,

        builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/.

        * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6.

        * builds/unix/configure.raw (version_info): Set to 9:17:3.


        * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x'
        and `scale_y'.
        * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'.


        * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H.
        * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.

2008-06-10  Werner Lemberg  <wl@gnu.org>

        * src/base/ftobjs.c (open_face): Check `clazz->init_face' and
        `clazz->done_face'.

2008-06-09  VaDiM  <s_sliva@rambler.ru>

        Support debugging on WinCE.  From Savannah patch #6536; this fixes
        bug #23497.

        * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
        as a replacement for OutputDebugStringA (which WinCE doesn't have).
        Update all callers.
        (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
        environment variables.

2008-06-09  Werner Lemberg  <wl@gnu.org>

        * README.CVS: Updated.

        * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
        for newer versions of autoconf and friends.

2008-06-08  Werner Lemberg  <wl@gnu.org>

        * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
        `private_len' unsigned.

        * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
        it as such.
        (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.


        * src/base/ftstream.c (FT_Stream_Skip): Reject negative values.


        * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
        for sane value.
        Fix typo.


        * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.


        * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
        `last_point'.


        * src/sfnt/ttload.c (tt_face_load_max_profile): Limit
        `maxTwilightPoints'.

2008-06-06  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
        correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.

2008-06-03  Werner Lemberg  <wl@gnu.org>

        * include/freetype/ftcache.h (FTC_FaceID): Change type back to
        FT_Pointer.  Reported by Ian Britten <britten@caris.com>.

2008-06-02  Werner Lemberg  <wl@gnu.org>

        Emit header info for defined FreeType objects in reference.

        * src/tools/docmaker/content.py (re_header_macro): New regexp.
        (ContentProcessor::__init__): Initialize new dictionary `headers'.
        (DocBlock::__init__): Collect macro header definitions.

        * src/tools/docmaker/tohtml.py (header_location_header,
        header_location_footer): New strings.
        (HtmlFormatter::__init__): Pass `headers' dictionary.
        (HtmlFormatter::print_html_field): Don't emit paragraph tags.
        (HtmlFormatter::print_html_field_list): Emit empty paragraph.
        (HtmlFormatter::block_enter): Emit header info.

2008-06-01  Werner Lemberg  <wl@gnu.org>

        * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
        FT_INCREMENTAL_H): Added.

2008-05-28  Werner Lemberg  <wl@gnu.org>

        * src/tools/docmaker/sources.py (SourceBlock::__init__): While
        looking for markup tags, return immediately as soon a single one is
        found.

2008-05-28  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
        original, unscaled input values.  Confirmed by Greg Hitchcock from
        Microsoft.

2008-05-27  Werner Lemberg  <wl@gnu.org>

        * src/tools/docmaker/tohtml.py (block_footer_start,
        block_footer_middle): Beautify output.

2008-05-25  Werner Lemberg  <wl@gnu.org>

        * src/raster/ftraster.c (fc_black_render): Return 0 when we are
        trying to render into a zero-width/height bitmap, not an error code.

        * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
        of the graphics state for subglyphs to...
        (TT_Hint_Glyph): This function.
        Hinting instructions for a composite glyph apparently refer to the
        just hinted subglyphs, not the unhinted, unscaled outline.  This
        seems to fix Savannah bugs #20973 and (at least partially) #23310.

2008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
        `aface' is returned by FT_New_Face_From_FOND().  The patch was
        proposed by an anonymous reporter of Savannah bug #23204.

2008-05-18  Werner Lemberg  <wl@gnu.org>

        * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
        correction for pixel boundary.  Without this patch, the effect can
        be cumulative under certain circumstances, making glyphs taller and
        taller after each call.  This fixes Savannah bug #19976.

2008-05-18  Werner Lemberg  <wl@gnu.org>

        * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
        This fixes Savannah bug #23280.

        * docs/CHANGES: Updated.

2008-05-18  David Turner  <david@freetype.org>

        * src/psnames/psmodule.c (ft_wgl_extra_unicodes,
        ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
        ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
        declarations non-global.

        * src/type1/t1load.c: Add missing comment.

2008-05-17  Sam Hocevar  <samh>

        * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
        glyphs correctly.  Patch from Savannah bug #23277.

2008-05-16  Werner Lemberg  <wl@gnu.org>

        * docs/CHANGES: Updated.

2008-05-16  Sergey Tolstov  <stolstov@esri.com>

        Improve support for WGL4 encoded fonts.

        * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.

        * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
        <op_closepath>: `closepath' without a path is a no-op, not an error
        (cf. the PS reference manual).

        Reported by Martin McBride.

2008-05-15  Werner Lemberg  <wl@gnu.org>

        * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.

        * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
        which contains a single but empty entry.  This is technically
        invalid (since it must end with `return'), but...

        Reported by Martin McBride.

2008-05-14  Werner Lemberg  <wl@gnu.org>

        Finish fix of scaling bug of CID-keyed CFF subfonts.

        * include/freetype/internal/ftcalc.h, src/base/ftcalc.c
        (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
        functions.

        * src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
        provide global hinting data for both the top-font and all subfonts
        (with proper scaling).

        * src/cff/cffobjs.c (cff_make_private_dict): New function, using
        code from `cff_size_init'.
        (cff_size_init, cff_size_done, cff_size_select, cff_size_request):
        Use CFF_Internal and handle subfonts.
        (cff_face_init): Handle top-dict and subfont matrices correctly;
        apply some heuristic in case of unlikely matrix concatenation
        results.  This has been discussed with people from Adobe (thanks
        goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
        and not correct.

        * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

        * src/cff/cffgload.c (cff_builder_init): Updated.

2008-05-04  Werner Lemberg  <wl@gnu.org>

        First steps to fix the scaling bug of CID-keyed CFF subfonts,
        reported by Ding Li on 2008/03/28 on freetype-devel.

        * src/base/cff/cffparse.c (power_tens): New array.
        (cff_parse_real): Rewritten to introduce a fourth parameter which
        returns the `scaling' of the real number so that we have no
        precision loss.  This is not used yet.
        Update all callers.
        (cff_parse_fixed_thousand): Replace with...
        (cff_parse_fixed_scaled): This function.  Update all callers.

2008-05-03  Werner Lemberg  <wl@gnu.org>

        * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
        transformation since it recursively calls FT_Load_Glyph.  This fixes
        Savannah bug #23143.

2008-04-26  Werner Lemberg  <wl@gnu.org>

        * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'

        Fix compilation with g++ 4.1 (with both `single' and `multi'
        targets).

        * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
        which is crossed by a `goto'.

2008-03-31  Werner Lemberg  <wl@gnu.org>

        Fix support for subsetted CID-keyed CFFs.

        * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
        FT_IS_CID_KEYED): New macros.

        * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
        maximum CID value in CID-keyed CFFs.
        Handle FT_FACE_FLAG_CID_KEYED flag.

        * docs/CHANGES: Document it.


        Fix CFF font matrix calculation and improve precision.

        * src/cff/cffparse.c (cff_parse_real): Increase precision if integer
        part is zero.
        (cff_parse_font_matrix): Simplify computation of `units_per_em';
        this prevents overflow also.

        * builds/symbian/*: New files.

2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
        synthesis.  For any face of a specified FOND, always the name for
        the first face was used.  Except of a FOND that refers multiple
        Type1 font files, wrong synthesized font names are not used at all,
        so this is an invisible bug.  A few limit checks are added too.

        * builds/mac/ftmac.c: Ditto.

2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Split compiler option to link Carbon
        frameworks to one option for CoreServices framework and another
        option for ApplicationServices framework.  The split options can be
        managed by GNU libtool to avoid unrequired duplication when FreeType
        is linked with other applications.  Suggested by Daniel Macks,
        Savannah bug #22366.

2008-02-18  Victor Stinner  <victor.stinner@haypocalc.com>

        Check for valid callback pointers.

2008-02-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
        handle by its value instead of ResError(), fix provided by Deron
        Kazmaier.  According to the Resource Manager Reference,
        GetResource(), Get1Resource(), GetNamedResource(),
        Get1NamedResource() and RGetResource() set noErr but return NULL
        handle when they can not find the requested resource.  These
        functions never return undefined values, so it is sufficient to
        check if the handle is not NULL.

        * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.

2008-02-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
        inclusion styles.  Now it always includes src/base/ftmac.c;
        builds/mac/ftmac.c is never included in any configuration.

        * builds/unix/configure.raw: Print warning if configure is executed
        with options to specify Carbon functionalities explicitly.

        * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
        included automatically and manual replacement is required.

2008-02-11  Werner Lemberg  <wl@gnu.org>

        * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
        (dos_setup), builds/freetype.mk (clean_project_dos,

2008-01-10  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
        where the number of contours in a simple glyph is zero (and which
        does contain an entry in the `glyf' table).  This fixes Savannah bug
        #21990.

2007-12-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Improvement of POSIX resource-fork accessor to load unsorted
        references in a resource.  In HelveLTMM (resource-fork PostScript
        Type1 font bundled with Mac OS X since 10.3.x), the appearance order
        of PFB chunks is not sorted; sorting the chunks by reference IDs is
        required.

        * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
        type to store a pair of reference ID and offset to the chunk.

        * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
        sort FT_RFork_Ref by their reference IDs.

        (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
        sorted by reference ID.

2007-12-14  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
        division too early; otherwise the most significant digit(s) of the
        final result are lost as the value is truncated to an integer.  This
        fixes Savannah bug #21794 (where the patch has been posted too).

2007-12-06  Fix  <4d876b82@gmail.com>

        Pass options from one configure script to another as-is (not
        expanded).  This is needed for options like
        --includedir='${prefix}/include'.

        * builds/unix/detect.mk, configure: Prevent argument expansion in
        call to the (real) `configure' script.

2007-12-06  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
        TT_USE_BYTECODE_INTERPRETER isn't defined.

2007-12-06  Werner Lemberg  <wl@gnu.org>

        There exist CFFs which contain opcodes for the Type 1 operators
        `hsbw' and `closepath' which are both invalid in Type 2 charstrings.
        However, it doesn't harm to support them.

        * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
        `cff_op_closepath.'
        (cff_argument_counts): Ditto.

        (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
        and 13 (hsbw) which are invalid in Type 2 charstrings.

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
        support new pathname syntax `..namedfork/rsrc' to access a resource
        fork on Mac OS X.  The legacy syntax `/rsrc' does not work on
        case-sensitive HFS+.
        (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
        buffer size to store a pathname.
        * include/freetype/internal/ftrfork.h: Increment the number of
        resource fork guessing rule.

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/unix/configure.raw: Improve the compile tests to search

        * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
        proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        The documents and comments for Mac OS X are improved by Sean

        system version specified by MACOSX_DEPLOYMENT_TARGET.

2007-12-04  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to

2007-12-04  Graham Asher  <graham.asher@btinternet.com>

2007-11-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
        not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
        cannot mmap() the specified file and cannot seek to head of the
        specified file, it returns NULL stream and FT_Open_New() returns the
        error immediately.  On MacOS, most legacy MacOS fonts fall into such
        a scenario because their data forks are zero-sized and cannot be
        sought.  To proceed to guessing of resource fork fonts, the
        functions for legacy MacOS font must properly handle the NULL stream
        returned by FT_New_Stream().

        * src/base/ftobjs.c (IsMacBinary): Return error
        FT_Err_Invalid_Stream_Operation immediately when NULL stream is
        passed.
        (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
        to fallback.  Originally, legacy MacOS font is tested in the cases
        of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
        or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
        .dfont header is combined).  Now the case of
        FT_Err_Cannot_Open_Stream is included.

        * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
        skip FT_Stream_Seek(), which seeks to the head of stream, and
        proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
        for a NULL stream causes a Bus error on Mac OS X.
        (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
        immediately if passed stream is NULL.
        (raccess_guess_apple_single): Ditto.

2007-11-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Fix for Carbon incompatibilities since Mac OS X 10.5,
        proposed by Sean McBride.

        * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.

        * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
        FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling
        Carbon functions from a forked process is classified as unsafe
        by Apple.  All Carbon-dependent functions should be deprecated.

        * src/base/ftmac.c: Use essential header files
        <CoreServices/CoreServices.h> and
        <ApplicationServices/ApplicationServices.h> instead of
        all-in-one header file <Carbon/Carbon.h>.

        Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
        genuine macro PATH_MAX.

        Add fallback macro for kATSOptionFlagsUnRestrictedScope which
        is not found in Mac OS X 10.0.

        Multi-character constants ('POST', 'sfnt' etc) are replaced by
        64bit constants calculated by FT_MAKE_TAG() macro.

        For the index in the segment of resource fork, new portable
        type ResourceIndex is introduced for better compatibility.
        This type is since Mac OS X 10.5, so it is defined as short
        when built on older platforms.

        (FT_ATSFontGetFileReference): If build target is only the systems
        10.5 and newer, it calls Apple genuine ATSFontGetFileReference().

        (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
        and newer or 64bit platform, because legacy type FSSpec type is
        removed completely.

        (FT_New_Face_From_FSSpec): Ditto.

2007-11-01  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This
        fixes Savannah bug #21485.

2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>

        * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
        can handle the font at all, then check `face_index'.  Otherwise, the
        driver might return the wrong error code.  This fixes Savannah bug
        #21468.

2007-10-21  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
        support for bit 8 of the `fsSelection' field in the `OS/2' table.
        MS is already using this; hopefully, this becomes part of OpenType
        1.5.
        Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
        (WWS_SUBFAMILY).

2007-10-20  Werner Lemberg  <wl@gnu.org>

        * src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
        Add `td.left' element to CSS.
        (toc_section_enter): Use it.

2007-10-18  David Turner  <david@freetype.org>

        * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
        functions related to cmap type 14 support to the
        `FT_Object_ActionName' scheme:

          FT_Get_Char_Variant_index     -> FT_Face_GetCharVariantIndex

        * docs/CHANGES: Document them.

2007-05-04  <harry@kdevelop.org>

        * builds/unix/ftsystem.c (FT_Stream_Open): Handle return value 0 of

        * Version 2.3.3 released.
        =========================


        Tag sources with `VER-2-3-3'.

        * docs/CHANGES: Mention CVE-2007-1351.

2007-04-03  David Turner  <david@freetype.org>

        * src/base/ftobjs.c (FT_Set_Char_Size): As suggested by James Cloos,
        if one of the resolution values is 0, treat it as if it were the
        same as the other value.

2007-04-02  David Turner  <david@freetype.org>

        Add special code to detect `extra-light' fonts and do not snap their
        stem widths too much to avoid bizarre hinting effects.

        * src/autofit/aflatin.h (AF_LatinAxisRec): Add `standard_width' and
        `extra_light' members.

        * src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize
        them.
        (af_latin_metrics_scale_dim): Set `extra_light'.

2007-03-28  David Turner  <david@freetype.org>

        * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix zero-ing of the
        padding.

2007-03-28  Werner Lemberg  <wl@gnu.org>

        * src/bdf/bdflib.c (setsbit, sbitset): Handle values >= 128
        gracefully.
        (_bdf_set_default_spacing): Increase `name' buffer size to 256 and
        issue an error for longer names.  This fixes CVE-2007-1351.
        (_bdf_parse_glyphs): Limit allowed number of glyphs in font to the
        number of code points in Unicode.

        * builds/win32/visualc/index.html,
        builds/win32/visualc/freetype.dsp,
        builds/win32/visualc/freetype.vcproj, README: s/2.3.2/2.3.3/,

        (Ins_MD): Last regression fix.

        * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
        computations in order to ignore single-point contours.  These are
        never rasterized and correspond in certain fonts to mark-attach
        points that are very far from the glyph's real outline, ruining the
        computation.

        * src/autofit/afloader.c (af_loader_load_g): In the case of
        monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0.
        Otherwise code that uses them will most certainly ruin the fixed
        advance property.

        * docs/CHANGES, docs/VERSION.DLL, README, Jamfile (RefDoc): Update
        documentation and bump version number to 2.3.3.

        * builds/unix/configure.raw: Dequote `OS_INLINE' in comment of

        * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.

        * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
        s/2.3.0/2.3.1/.

        * builds/unix/configure.raw (version_info): Set to 9:12:3.


        * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
        (af_loader_load_g): Disable the warper (i.e., the light hinting
        improvements) to make a 2.3.1 bugfix release before introducing a
        new feature.  This should give us more time to tune and improve the
        warper for the next release.

        * docs/CHANGES: Update accordingly.

2007-01-25  David Turner  <david@freetype.org>

        For light auto-hinting, improve glyph advance widths and resurrect
        normal/full hinting to its normal quality.

        * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
        and `xmax_delta'.
        * src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
        and `xmax_delta'.

        * src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
        preprocessor conditional with if-clause, handling both light and
        normal mode.

        * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
        (af_warper_compute): Handle `xmin_delta' and `xmax_delta'.

        * docs/release: Updated -- Savannah uses a new uploading scheme.

2007-01-25  David Turner  <david@freetype.org>

        * src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.

        * src/cff/cffgload.c (cff_decoder_parse_charstrings)

        functions.

        * docs/CHANGES: Document light auto-hinting improvement.

2007-01-25  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
        correctly in a sanity check.  Since this function is only used to
        load local and global functions, any charstring that called the last
        local/global function would fail otherwise.  This fixes Savannah bug
        #18867.

        * docs/CHANGES: Document it.

2007-01-23  David Turner  <david@freetype.org>

        * src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
        prevented compilation when disabling both the unpatented and the
        bytecode interpreter in the TrueType font driver.

        not necessarily a final version, but it seems to work well.

        * src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
        Disable code.
        (af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
        * src/autofit/aftypes.h: Activate AF_USE_WARPER.

        * src/autofit/afwarp.c (AF_WarpScore): Tune table.
        (af_warper_compute_line_best): Fix array size of `scores'.
        (af_warper_compute): Better handling of border cases.
        * src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
        and `X2'.

2007-01-21  Werner Lemberg  <wl@gnu.org>

        af_glyph_hints_dump_edges): Ditto.

        * src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in
        `modules.cfg').

        * src/sfnt/ttsbit0.h: Remove.

        * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.

2007-01-12  David Turner  <david@freetype.org>

        * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
        bug in the bitmap emboldener if the pitch of the source bitmap is
        much larger than its width.

        * src/truetype/ttinterp.c (Update_Max): Fix aliasing-related

        crash with some Mac OS X .dfont files.  Submitted by Masatake
        Yamato.

        * autogen.sh: Small fix to get it working on Mac OS X properly:
        The issue is that GNU libtool is called `glibtool' on this platform,
        and we must call `glibtoolize', since `libtoolize' doesn't exist.

        Type 11 fonts.
        Scan for `/sfnts' token.

2007-01-07  Werner Lemberg  <wl@gnu.org>

        * src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts.

2007-01-06  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_index_init): Remove unused variable.
        (cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.

2007-01-04  David Turner  <david@freetype.org>

        * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
        correctly.  This fixes Savannah bug #17876.


        Do not allocate interpreter-specific tables in memory if we are not
        going to load glyphs with the bytecode interpreter anyway.

        * src/truetype/ttgload.c (tt_loader_init): Load execution context
        only if glyph is hinted.
        Updated.
        * src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
        and `cvs_ready'.
        Add `tt_size_ready_bytecode' declaration.
        * src/truetype/ttobjs.c (tt_size_done_bytecode,
        tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
        (tt_size_init): Move most code into `tt_size_init_bytecode'.
        (tt_size_done): Move most code into `tt_size_done_bytecode'.
        (tt_size_reset): Move some code to `tt_size_ready_bytecode'.


        Don't extract the metrics table from the SFNT font file.  Instead,
        reparse it on each glyph load.  The runtime difference is not
        noticeable, and it can save a lot of heap memory when memory-mapped
        files are not used.

        * include/freetype/internal/tttypes.h (TT_FaceRec): Add members
        `horz_metrics_offset' and `vert_metrics_ofset'.
        * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
        Updated.


        * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.


        Do not load the CFF index offsets into memory, since this wastes a
        *lot* of heap memory with large Asian CFF fonts.  There is no
        significant performance loss.

        * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
        * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
        `data_size'.
        (CFF_CharsetRec): Add field `num_glyphs'.

        * src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
        cff_charset_cid_to_gindex): New functions.
        (cff_new_index): Renamed to...
        (cff_index_init): This.  Update all callers.
        Updated -- some code has been moved to `cff_index_load_offsets'.
        (cff_done_index): Renamed to...
        (cff_index_done): This.  Update all callers.
        (cff_index_get_pointers, cff_index_access_element): Updated to use
        stream offsets.
        (cff_charset_compute_cids): Set `num_glyphs' field.
        (cff_encoding_load): Updated.

        * src/cff/cffgload.c (cff_slot_load): Updated.

2007-01-04  David Turner  <david@freetype.org>

        * docs/INSTALL.UNIX: Simplify some parts, add reference to
        autogen.sh and pointer to README.CVS.

        * README.CVS: Add common problem description and solution
        when running autogen.sh.

        * docs/INSTALL: Add reference to MacOS X.

        * docs/MAKEPP, docs/INSTALL.MAC: New documentation files.

        * docs/TODO: Remove obsolete items.

        * src/raster/ftraster.c: (TRaster_Instance): Replace it with...
        (TWorker): This.
        Remove `count_table' and `memory'.
        Make `grays' a pointer.
        (TRaster): New structure.
        (count_table): New static array.
        (RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
        Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
        ft_black_set_mode, ft_black_render): Updated.
        (ft_black_init): Don't initialize `count_table'.
        (ft_black_reset): Use the render pool.  This saves about 6KB of
        heap space for each FT_Library instance.

        * src/smooth/ftgrays.c (TRaster): Replaced with...
        (TWorker): This.
        Remove `memory'.
        (TRaster): New structure.

        (RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
        gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
        gray_render_span, gray_raster_render): Updated.
        (gray_raster_reset): Use the render pool.  This saves about 6KB of
        heap space for each FT_Library instance.

        * src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
        src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
        src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
        FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
        the optimization is no longer experimental.

        * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
        Remove a typo that results in no hinting and a memory leak with some
        large Asian CFF fonts.

        * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
        which happens when FT_Done_Library is called with still opened
        CFF_Faces in it.  We need to close all faces before destroying the
        modules, or else some bad things (memory leaks) may happen.

2007-01-02  Werner Lemberg  <wl@gnu.org>

        * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
        Remove compiler warning.

2007-01-02  David Turner  <david@freetype.org>

        * src/sfnt/sfobjs.c: Add documentation comment.

2006-12-31  Masatake YAMATO  <jet@gyve.org>

        * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New
        function.
        Check uniqueness of the gid pairs.
        (gxv_kern_subtable_fmt0_validate): Move some code to
        `gxv_kern_subtable_fmt0_pairs_validate'.

2006-12-22  David Turner  <david@freetype.org>

        * src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
        warnings.

        * builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
        to avoid deprecation warnings with Visual C++ 8.

2006-12-16  Anders Kaseorg  <anders@kaseorg.com>

        * src/base/ftlcdfil.c (FT_Library_SetLcdFilter)
        [FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * include/freetype/internal/services/svotval.h: Add `volatile' to
        sync with the modification by Jens Claudius on 2006-08-22; cf.
          http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c: Specialized for Mac OS X only.
        * builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
        * builds/unix/configure.raw: Ditto.  When explicit switches for
        FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
        builds/mac/ftmac.c is used instead of default src/base/ftmac.c.

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.
        * builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c
        instead of src/base/ftmac.c
        * builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
        * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
        * builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
        that cannot be built at present.

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftobjs.c: Improvement of resource fork handler for
        POSIX, cf.
          http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
        (Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
        format or .dfont, to simulate the face index number counted by ftmac.c.
        (IsMacResource): Return the number of scalable faces correctly.

2006-12-10  Werner Lemberg  <wl@gnu.org>

        * builds/toplevel.mk (version): Protect against `distclean' target.

2006-12-09  Werner Lemberg  <wl@gnu.org>

        * builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'
        or `type'.

        * builds/freetype.mk (version): Extracted from freetype.h, using
        GNU make's built-in string functions.
        (refdoc): Use $(version) instead of static version number.

2006-12-08  Werner Lemberg  <wl@gnu.org>

        * builds/toplevel.mk (dist): Extract version number from freetype.h.

2006-12-08  Vladimir Volovich  <vvv@vsu.ru>

        * src/tools/apinames.c (State): Remove final comma in structure --
        xlc v5 under AIX 4.3 doesn't like this.

2006-12-07  David Turner  <david@freetype.org>

        * src/autofit/afloader.c (af_loader_load_g): Small adjustment
        to the spacing of auto-fitted glyphs.  This only impacts rare
        cases (e.g., Arial Bold at rather small character sizes).

2006-12-03  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.

2006-12-01  Werner Lemberg  <wl@gnu.org>

        * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are
        encoded in UTF-16BE.  Patch from Rajeev Pahuja <rpahuja@esri.com>.
        (tt_name_entry_ascii_from_ucs4): Removed.


        * include/freetype/ftxf86.h: Fix and extend comment so that it
        appears in the documentation.

        * include/freetype/ftchapters.h: Add `font_format' section.


        * src/tools/docmaker/tohtml.py (HtmlFormatter::index_exit): Add link
        to TOC in index page.

2006-11-28  David Turner  <david@freetype.org>

        * src/smooth/ftgrays.c (gray_raster_render): Return 0 when we are
        trying to render into a zero-width/height bitmap, not an error code.

        * src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.

        * src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType
        ones instead.

        * src/autofit/afhints.c (af_glyph_hints_dump_segments): Remove unused
        variable.

2006-11-26  Pierre Hanser  <hanser@club-internet.fr>

        * src/truetype/ttobjs.c (tt_face_init): Protect against NULL pointer.

2006-11-25  David Turner  <david@freetype.org>

        * src/autofit/afhints.c (af_glyph_hints_dump_points,
        af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
        Add stubs to link the `ftgrid' test program when debugging is
        disabled in the auto-hinter.

2006-11-23  David Turner  <david@freetype.org>

        * src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,
        src/autofit/aftypes.h: Miscellaneous auto-hinter improvements.

        * src/autofit/afhints.c (af_glyph_hints_dump_segments) [AF_DEBUG]:
        Emit more sensible information.

        * src/autofit/afhints.h (AF_SegmentRec): Add `height' member.

        * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Improve
        rounding of blue values.
        (af_latin_hints_compute_segments): Hint segment heights.
        (af_latin_hints_link_segments): Reduce `len_score' value.
        (af_latin_hints_compute_edges): Increase `segment_length_threshold'
        value and use `height' member for comparisons.
        (af_latin_hint_edges): Extend logging message.
        Improve handling of remaining edges.

2006-11-22  Werner Lemberg  <wl@gnu.org>

        Fix Savannah bug #15553.

        * src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
        program after a change from mono to grayscaling (and vice versa).
        Use correct constant for comparison to get `exec->grayscale'.

2006-11-18  Werner Lemberg  <wl@gnu.org>

        Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
        test for a valid glyph index must be deferred to the font drivers.
        This patch fixes Savannah bug #18301.

        * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
        * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
        (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
        src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c
        (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),
        src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
        (FNT_Load_Glyph): Check validity of `glyph_index'.

2006-11-13  David Turner  <david@freetype.org>

        * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
        `enhancements' are still too buggy for general use.

        * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
        FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros
        when building the library to change the default LCD filter to be
        used.  This is only useful for experimentation.

        * include/freetype/ftlcdfil.h: Update documentation.

2006-11-10  David Turner  <david@freetype.org>

        * src/smooth/ftsmooth.c: API change for the LCD
        filter.  The FT_LcdFilter value is an enumeration describing which
        filter to apply, with new values FT_LCD_FILTER_LIGHT and
        FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
        algorithm which produces strong color fringes for everything
        except very-well hinted text).

        * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
        second parameter to an enum type.

        * src/base/ftlcdfil.c (USE_LEGACY): Define.
        (_ft_lcd_filter): Rename to...
        (_ft_lcd_filter_fir): This.
        Update parameters.
        (_ft_lcd_filter_legacy) [USE_LEGACY]: New filter function.
        (FT_Library_Set_LcdFilter): Update parameters.
        Handle new filter modes.

        * include/internal/ftobjs.h: Include FT_LCD_FILTER_H.
        (FT_Bitmap_LcdFilterFunc): Change third argument to `FT_Library'.
        (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering
        callback and update other fields.

        * src/smooth/ftsmooth.c (ft_smooth_render_generic)
        [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
        Other minor improvements.

        * src/autofit/aflatin.c: Various tiny improvements that drastically
        improve the handling of serif fonts and of LCD/LCD_V hinting modes.
        (af_latin_hints_compute_edges): Fix typo.
        (af_latin_compute_stem_width): Take better care of diagonal stems.

2006-11-09  David Turner  <david@freetype.org>

        * src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
        typo which created a variable-used-before-initialized bug.

2006-11-07  Zhe Su  <james.su@gmail.com>

        * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
        also.

2006-11-03  Werner Lemberg  <wl@gnu.org>

        * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

2006-11-02  David Turner  <david@freetype.org>

        Add a few tweaks to better handle serif fonts.
        Add more debugging messages.

        * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
        segments that are less than 1.5 pixels high.  This gets rid of
        *many* corner cases with serifs.
        (af_latin_align_linked_edge): Add logging message.
        (af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
        Add logging messages.
        Handle AF_EDGE_FLAG flag specially.

        * src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
        _af_debug_disable_blue_hints, and _af_debug_hints variables.

        * src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
        Update external declarations.
        (af_corner_orientation, af_corner_is_flat): Replaced by...

        * include/freetype/internal/ftcalc.h (ft_corner_orientation,
        ft_corner_is_flat): These declarations.

        * src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
        Comment out.  Replaced by...

        * src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
        These functions.  Update all callers.
        (FT_Add64) [!FT_LONG64]: Simplify.

        * src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
        (af_direction_compute): Add a missing FT_ABS call.  This bug caused
        production of garbage by missing lots of segments.

        * src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.

        * src/autofit/afloader.c (af_loader_init, af_loader_done)
        [AF_DEBUG]: Set _af_debug_hints.


        * src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H.
        (psh_corner_is_flat, psh_corner_orientation): Use ft_corner_is_flat
        and ft_corner_orientation.


        * src/gzip/inftrees.c (huft_build): Remove compiler warning.

2006-10-24  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_encoding_load): Remove unused variable.

        * src/base/ftobjs.c (FT_Select_Charmap): Disallow FT_ENCODING_NONE
        as argument.

2006-10-23  Zhe Su  <zsu@novell.com>

        * src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
        better deal with broken Asian fonts with strange glyphs, having
        self-intersections and other peculiarities.  The used algorithm is
        based on the nonzero winding rule.

2006-10-23  David Turner  <david@freetype.org>

        Speed up the CFF font loader.  With some large CFF fonts,
        FT_Open_Face is now more than three times faster.

        * src/cff/cffload.c (cff_get_offset): Removed.
        (cff_new_index): Inline functionality of `cff_get_offset'.
        (cff_charset_compute_cids, cff_charset_free_cids): New functions.
        (cff_charset_done): Call `cff_charset_free_cids'.
        (cff_charset_load): Call `cff_charset_compute_cids'.
        (cff_encoding_load) <Populate>: Ditto, to replace inefficient loop.

        * src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX
        with FT_NEXT_XXX.


        Speed up the Postscript hinter, with more than 100% speed increase
        on my machine.

        * src/pshinter/pshalgo.c (psh_corner_is_flat,
        psh_corner_orientation): New functions.
        (psh_glyph_compute_inflections): Merge loops for efficiency.
        Use `psh_corner_orientation'.
        (psh_glyph_init): Use `psh_corner_is_flat'.
        (psh_hint_table_find_strong_point): Renamed to...
        (psh_hint_table_find_strong_points): This.
        Rewrite, adding argument to handle all points at once.
        Update all callers.
        (PSH_MAX_STRONG_INTERNAL): New macro.
        (psh_glyph_interpolate_normal_points): Rewrite for efficiency.

2006-10-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (FT_New_Face_From_FOND): Initialize variable
        `error' with FT_Err_Ok.

        * include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.


        Add a new API to support color filtering of subpixel glyph bitmaps.
        In a default build, the function `FT_Library_SetLcdFilter' returns
        `FT_Err_Unimplemented_Feature'; you need to #define
        FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
        real implementation.

        * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

        * include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
        typedef.
        (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
        `lcd_filter_weights' and `lcd_filter'.

        * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
        `hmul' and `vmul'.

        Handle subpixel rendering.
        Simplify function.
        (ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
        (ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.

        * include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
        pointing to <freetype/ftlcdfil.h>.

        * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
        vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.

        * modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.

2006-09-26  David Bustin

        * src/pfr/pfrobjs.c (pfr_face_get_kerning): Skip adjustment bytes

        * src/autofit/afhints.h (AF_HINTS_DO_HORIZONTAL,
        AF_HINTS_DO_VERTICAL, AF_HINTS_DO_ADVANCE): New macros to disable
        horizontal and vertical hinting for the purpose of debugging the
        auto-fitter.

        _af_debug_disable_vert_hints) [AF_DEBUG]: New global variables.

        * src/autofit/aftypes.h [AF_DEBUG]: Declare above variables.

        * include/freetype/config/ftoption.h, devel/ftoption.h
        (FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
        we want to compile LCD-optimized rendering code (à la ClearType) or
        not.  The macro *must* be disabled in default builds of the library
        for patent reasons.

        * src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
        LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
        isn't defined at compile time.  This only changes the content of the
        rendered glyph to match the one of normal gray-level rendering,
        hence clients should not need to be modified.

        * docs/CHANGES: Updated.

2006-09-18  Garrick Meeker  <garrick@digitalanarchy.com>

        * src/base/ftmac.c (FT_New_Face_From_FOND): Fall back to SFNT if

        (platform,encoding) pair, with language_id != English.

        If the font uses another name entry with language_id == English, it
        will be selected correctly, though.

        * src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
        selection for `mingli.ttf'.

2006-09-05  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size'
        values which have the upper two bytes set to 0xFF instead of 0x00
        (as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
        `HAN NOM B.ttf').

        * src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.

2006-09-05  David Turner  <david@freetype.org>

        loader.

        * src/smooth/ftgrays.c: Optmize the performance of the anti-aliased

        QSORT_THRESHOLD):
        Removed.
        (gray_shell_sort, gray_quick_sort, gray_check_sort,

        (ps_tocoordarray): Allow `coords' argument to be NULL if we just
        want to skip the array.
        (ps_tofixedarray): Allow `values' argument to be NULL if we just
        want to skip the array.

        * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Add support
        for (partially commented out) othersubrs 19-25, 27, and 28.
        (t1_decoder_init): Initialize new fields `face' and `buildchar'.

        `keywords_encountered'.
        (T1_PRIVATE, T1_FONTDIR_AFTER_PRIVATE): New macros.

        * src/type1/t1tokens.h [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: New
        entries for parsing /NDV, /CDV, and /DesignVector.

2006-07-07  Werner Lemberg  <wl@gnu.org>

        Add many checks to protect against malformed PCF files.

        * src/pcf/pcfdrivr.c (PCF_Face_Done): Protect against NULL pointers.
        (PCF_Face_Init): Add calls to PCF_Face_Done in case of errors.

        * src/pcf/pcfread.c (pcf_read_TOC): Protect against malformed table
        data and check that tables don't overlap (using a simple
        bubblesort).
        (PCF_METRIC_SIZE, PCF_COMPRESSED_METRIC_SIZE, PCF_PROPERTY_SIZE):
        New macros which give the size of data structures in the data
        stream.
        (pcf_get_properties): Use rough estimates to get array size limits.
        Assign `face->nprops' and `face->properties' earlier so that a call

        Protect against invalid string offsets.
        (pcf_get_metrics): Clean up code.
        Adjust tracing message levels.
        Use rough estimate to get array size limit.

        Adjust tracing message levels.
        Use rough estimates to get offset limits.
        (pcf_get_encodings): Adjust tracing message level.
        (pcf_get_accel): Clean up code.

2006-06-26  Werner Lemberg  <wl@gnu.org>

        * src/bdf/bdfdrivr.c (BDF_Face_Init): Handle fonts correctly which
        don't have a POINT_SIZE property.  This fixes Savannah bug #16914.

2006-06-26  Jens Claudius  <jens.claudius@yahoo.com>

        * src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15.
        (t1_decoder_parse_charstrings): Operator with
        opcode 15 pops its two arguments.
        Handle the case where the pops of an othersubr may be part of a
        subroutine.
        Handle unknown othersubrs gracefully: count their operands and let
        the following pop operators push the operands as the results onto
        the Type1 stack.
        Improve handling of setcurrentpoint opcode.

2006-06-25  Jens Claudius  <jens.claudius@yahoo.com>

        The Type 1 parser now skips over top-level procedures as required
        for a `Simplified Parser'.  This makes the parser more robust as it
        doesn't poke around in PostScript code.  Additionally, it makes the
        FontDirectory hackery in src/type1/t1load.c unnecessary.

        * src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
        (skip_literal_string): Add FT_Error as return value.
        Handle escapes better.
        (skip_string): Add FT_Error as return value.
        Don't set `parser->error' but return error code directly.
        (skip_procedure): New function.
        (ps_parser_skip_PS_token): Handle procedures.
        Update code.
        (ps_parser_to_token): Update code.
        (ps_parser_load_field_table): Handle bbox entries also.

        * src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
        Add commented-out code for synthetic fonts.

2006-06-24  Eugeniy Meshcheryakov  <eugen@univ.kiev.ua>

        Fix two hinting bugs as reported in
        http://lists.gnu.org/archive/html/freetype-devel/2006-06/msg00057.html.

        * src/truetype/ttinterp.c (Ins_SHC): Fix computation of
        `first_point' and `last_point' in case of composite glyphs.
        (Ins_IUP): Fix computation of `end_point'.

2006-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
        Mac.  The original patch was written by David Sachitano and Lawrence
        Coopet, and modified by Sean McBride for MPW compatibility.  Only
        required data are converted; unused data are left in big endian.

        * src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
        Mac OS X platforms.
        (OS_INLINE): Undefine before definition.

        FontAssociation table in FOND resource.
        (count_faces_scalable): Insert EndianS16_BtoN to parse the header
        and fontSize at each entry of FontAssociation table in FOND
        resource.
        (parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to parse
        ffStylOff of FamilyRecord header of FOND resource, the header,
        fontSize, fontID at each entry of FontAssociation table, and
        StyleMapping table.
        (count_faces): Call `HUnlock' after all FOND utilization.

2006-06-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Public API of TrueTypeGX, OpenType, and classic kern table validator
        should return `FT_Err_Unimplemented_Feature' if validation service
        is unavailable (disabled in `modules.cfg').  It is originally
        suggested by David Turner, cf.
        http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

        * src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return
        FT_Err_Unimplemented_Feature if TrueTypeGX validation service is
        unavailable.
        (FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if
        classic kern table validation service is unavailable.

        * src/base/ftotval.c (FT_OpenType_Validate): Return
        FT_Err_Unimplemented_Feature if OpenType validation service is
        unavailable.

        errors.

2006-06-07  David Turner  <david@freetype.org>

        * src/type1/t1afm.c (KERN_INDEX): Make it more robust.
        (T1_Read_Metrics): Fix memory leak which happened when the metrics
        file doesn't have kerning pairs.  This fixes Savannah bug #16768.

2006-06-06  David Turner  <david@freetype.org>

        Fix memory leak described in Savannah bug #16759.

        We change `ps_unicodes_init' so that it also takes a
        `free_glyph_name' callback to release the glyph names returned by
        `get_glyph_name'

        * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
        Renamed to ...
        (PS_GetGlyphNameFunc): This.
        (PS_FreeGlyphNameFunc): New typedef.
        (PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.

        * src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
        argument.
        (cff_sid_free_glyph_name): New function.
        (cff_cmap_unicode_init): Updated.

        PS_FreeGlyphNameFunc and use it.


2006-06-04  David Turner  <david@freetype.org>

        * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
        `item_size == 0' as well -- though this sounds weird, it can
        theoretically happen.  This fixes Savannah bug #16669.

        * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
        of `face->num_glyphs' which missed the last glyph, due to
        the offset-by-1 computation, since the PFR format doesn't
        guarantee that glyph index 0 corresponds to the `missing
        glyph.  This fixes Savannah bug #16668.

2006-05-25  Werner Lemberg  <wl@gnu.org>

        * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
        `-no-undefined'.  Reported by Christian Biesinger.

2006-05-19  Brian Weed  <bw@imaginengine.com>

        * builds/win32/visualc/freetype.dsp: Release libraries no longer
        have debug information, and debug libraries use `C7 compatible'
        debug info.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        Apply patch by Derek Clegg to fix two memory leaks in the MacOS
        resource fork handler.  This fixes Savannah bug #16631.

        * src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
        `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

        Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * build/unix/configure.raw: Add a fallback to disable Carbon
        dependency, if configured with no options on Mac OS X.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        * src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
        its content cannot be parsed as supported font.  This fixes
        the second part of Savannah bug #16590.

2006-05-18  Werner Lemberg  <wl@gnu.org>

        * src/truetype/ttgload.c (TT_Load_Composite_Glyph)
        [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

2006-05-17  David Turner  <david@freetype.org>

        This is a major patch used to drastically improve the performance of
        loading glyphs.  This both speeds up loading the glyph vectors
        themselves and the auto-fitter module.

        We now use inline assembler code with GCC to implement `FT_MulFix',
        which is probably the most important function related to the
        engine's performance.

        The resulting speed-up is about 25%.


        * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
        `cursor' and `limit'.

        * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
        New functions.
        (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
        [TEST]: Remove.

        * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
        code.

        * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
        `FT_ZERO'
        (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
        (af_glyph_hints_reload: Rewrite recognition of weak points.

        * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
        constant values out of the loops.

        * src/autofit/aftypes.h: Updated.

        * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

        * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
        product to get orientation.

        * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
        (FT_Stream_OpenGzip): Use it to handle small files directly in
        memory.

        * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
        Improve performance.

        * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
        `limit'.

        (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
        TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
        exceedingly large values of number of contours.  Speed up by
        reducing the number of loops.

        * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.


        * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
        used to detect rogue clients from 4 to 16.  This is to prevent some
        segmentation faults with fonts like `KozMinProVI-Regular.otf' which
        comes from the Japanese Adobe Reader Asian Font pack.

2007-05-17  Werner Lemberg  <wl@gnu.org>

        * src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
        fixes the first part of Savannah bug #16590.

2006-05-16  Werner Lemberg  <wl@gnu.org>

        * docs/PROBLEMS: Updated icl issues.
