        * builds/unix/configure.raw: Use `x"${xxx}" != xno' style.

2014-03-04  Werner Lemberg  <wl@gnu.org>

        Minor fix for `make devel'.

        * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use
        pkg-config for bzip2 since not all GNU/Linux distributions have
        `bzip2.pc' (and the header file `bzlib.h' is located in /usr/include
        normally).

2014-03-04  Sean McBride  <sean@rogue-research.com>

        Fix several clang static analyzer dead store warnings.

        * src/autofit/afhints.c (af_glyph_hints_reload,

2014-03-03  Werner Lemberg  <wl@gnu.org>

        Rewrite library option handling in `configure'.

        o Introduce `auto' value for `--with-XXX' library options; this is
          now the default.

        o First use `pkg-config' for library detection, then fall back to
          other tests.

        * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
        --with-harfbuzz): Rewrite.
        Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'
        variables to collect data for `freetype2.pc' and `freetype-config'.
        (FT2_EXTRA_LIBS): Renamed to ...
        (ft2_extra_libs): This since it gets no longer substituted.
        (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG):
        New output variables, replacing `XXX_PKG' and `LIBXXX'.
        Add notice at the end of `configure' showing the library
        configuration.

        * builds/unix/freetype-config.in (--static): New command line
        option.
        (libs): Updated.
        (staticlibs): New variable, to be used if `--static' is given.
        * builds/doc/freetype-config.1: Document `--static'.

        * builds/unix/freetype2.in, builds/unix/unix-def.in: Updated.

2014-03-01  Werner Lemberg  <wl@gnu.org>

        Avoid `long long' warnings with older gcc compilers.
        Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.

        * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for
        versions < 4.6.  This is especially needed for Max OS X since this
        OS runs a gcc variant (or emulation) based on version 4.2.1.

2014-03-01  Werner Lemberg  <wl@gnu.org>

        * docs/INSTALL.CROSS: Revised and updated.

2014-03-01  Werner Lemberg  <wl@gnu.org>

        Make `make clean' remove `freetype2.pc'.

        This is a generated file at build time, not configure time.

        * builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...
        (CLEAN): This variable.

2014-03-01  Werner Lemberg  <wl@gnu.org>

        Use pkg-config for detecting libpng and libbz2 also.

        * builds/unix/configure.raw (HAVE_PKG): New variable.
        Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/.
        Search for libpng using `pkg-config'.
        Fix definition of `LIBHARFBUZZ' variable.
        * builds/unix/freetype-config.in ($libs): Updated.
        * builds/unix/freetype2.in: Add `URL' field.
        Update `Requires.private' and `Libs.private'.
        * builds/unix/unix-def.in: Updated.

2014-03-01  Werner Lemberg  <wl@gnu.org>

        Add configure support for HarfBuzz.

        * builds/unix/pkg.m4: New file.
        * builds/unix/configure.raw: Search for libharfbuzz using
        `pkg-config'.
        Add `--without-harfbuzz' option.
        * builds/unix/freetype-config.in, builds/unix/freetype2.in,
        builds/unix/unix-def.in (freetype-config, freetype2.pc): Handle
        HarfBuzz.

        * docs/INSTALL.UNIX: Document interdependency of Freetype with
        HarfBuzz.

2014-02-28  Alexei Podtelezhnikov  <apodtele@gmail.com>

        [cff] Math simplifications.

        * src/cf2blues.c (cf2_blues_init): Use `FT_MulDiv'.
        * src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division.

2014-02-28  Dave Arnold  <darnold@adobe.com>

        [cff] Fix Savannah bug #41697, part 2.

        * src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
        cf2_initGlobalRegionBuffer): It is possible for a charstring to call
        a subroutine if no subroutines exist.  This is an error but should
        not trigger an assert.  Split the assert to account for this.

2014-02-28  Dave Arnold  <darnold@adobe.com>

        [cff] Fix Savannah bug #41697, part 1.

        * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is
        invalid.  In this case, it is not safe to use the length of
        `hStemHintArray'; the exception has already been recorded in
        `hintMask'.

2014-02-26  Werner Lemberg  <wl@gnu.org>

        [sfnt] Fix Savannah bug #41696.

        * src/sfnt/ttcmap.c (tt_cmap0_validate, tt_cmap2_validate,
        tt_cmap4_validate, tt_cmap14_validate): Fix limit tests.

2014-02-26  Werner Lemberg  <wl@gnu.org>

        [winfnt] Fix Savannah bug #41694.

        * src/winfonts/winfnt.c (FNT_Load_Glyph): Check glyph offset.

2014-02-26  Werner Lemberg  <wl@gnu.org>

        [cff] Fix Savannah bug #41693.

        * src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.

2014-02-26  Werner Lemberg  <wl@gnu.org>

        [bdf] Fix Savannah bug #41692.

        bdflib puts data from the input stream into a buffer in chunks of
        1024 bytes.  The data itself gets then parsed line by line, simply
        increasing the current pointer into the buffer; if the search for
        the final newline character exceeds the buffer size, more data gets
        read.

        However, in case the current line's end is very near to the buffer
        end, and the keyword to compare with is longer than the current
        line's length, an out-of-bounds read might happen since `memcmp'
        doesn't stop properly at the string end.

        * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
        stop at string ends.

2014-02-17  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

        [autofit] Fix `make multi' compilation.

          https://code.google.com/p/sumatrapdf/source/browse/trunk/ext/_patches/freetype2.patch?spec=svn8620&r=8620#87

        with slight modifications.

        * src/type1/t1parse.c (T1_Get_Private_Dict): Add heuristic test to
        handle fonts that incorrectly use \r at the beginning of an eexec
        block.

2014-02-19  Simon Bünzli  <zeniko@gmail.com>

        variable.

2014-02-08  Werner Lemberg  <wl@gnu.org>

        Fix Windows build directories.

        The build target is now `windows' instead of `win32'.

        Problem reported by Nickolas George <darknova.clan@gmail.com>.

        * builds/modules.mk: Don't use `win32' and `win16' (!) but
        `windows'.

        * builds/windows/detect.mk, builds/windows/win32-def.mk:
        s/win32/windows/.

2014-02-08  Eugen Sawin  <esawin@mozilla.com>

2014-02-04  Werner Lemberg  <wl@gnu.org>

        Fix compilation with MinGW.

        Right now, compilation out of the box with latest MinGW is broken
        due to bugs in header files of mingwrt 4.0.3 in strict ANSI mode,
        cf.

          https://sourceforge.net/p/mingw/bugs/2024/
          https://sourceforge.net/p/mingw/bugs/2046/

        src/autofit/aflatin.c (af_latin_metrics_init_widths): Fix handling
        of alternative standard characters.
        This also fixes a compilation warning in non-debug mode.

2014-02-03  Werner Lemberg  <wl@gnu.org>

        [cff] Fix Savannah bug #41363.

        * src/cff/cf2ft.c (cf2_checkTransform): Convert assertion into
        parameter check.
        (cf2_decoder_parse_charstrings): Call `cf2_checkTransform' only if

2014-01-26  Werner Lemberg  <wl@gnu.org>

        [autofit] Introduce two more slots for standard characters.

        This is useful for OpenType features like `c2sc' (caps to small
        caps) that don't have lowercase letters by definition, or other
        features that mainly operate on numerals.

        * src/autofit/afscript.h: Add more standard characters.

        * src/tools/afblue.pl <Handling #endif>: Produce correct auxiliary
        enumeration names for generated `#else'.

        * src/autofit/afblue.h: Regenerated.

2014-01-06  Werner Lemberg  <wl@gnu.org>

        Add manual page for `freetype-config'.
        Contributed by Nis Martensen <nis.martensen@web.de>.

        * docs/freetype-config.1: New file.

        * builds/unix/unix-def.in (mandir): Define.

        <Handling #endif>: Use proper indentation for generated `#else'.

        * src/autofit/afblue.h: Regenerated.

2014-01-04  Werner Lemberg  <wl@gnu.org>

        [autofit] Fix Indic scripts.

        Split the single, incorrect Indic entry into separate scripts so
        that the covered ranges are the same: Bengali, Devanagari, Gujarati,
        Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
        Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove
        entries for Meetai Mayak and Sharada – the Unicode ranges were
        incorrect (and nobody has complained about that), fonts are scarce
        for those scripts, and the Indic auto-hinter support is rudimentary
        anyways.

        * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
        AF_CONFIG_OPTION_CJK.

        * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
        Use it, together with AF_CONFIG_OPTION_INDIC and
        AF_CONFIG_OPTION_CJK, to update.

        * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
        [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.
        Sort entries by tags.

2014-01-03  Werner Lemberg  <wl@gnu.org>

        [autofit] Thinko.

        * src/autofit/hbshim.c (af_get_char_index): Similar to

        [autofit] Fix handling of default coverages.

        With this commit, the implementation of coverage handling is
        completed.

        * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to
        do.
        Reject coverages which don't contain appropriate glyphs for blue
        zones.

2014-01-03  Werner Lemberg  <wl@gnu.org>

        [autofit] Fix handling of default coverages.

        * src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
        First handle non-default coverages, then the default coverage of the
        default script, and finally the other default coverages.

        [autofit] Better ftgrid support.

        * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add
        parameters `is_blue' and `blue_offset'.

2014-01-01  Werner Lemberg  <wl@gnu.org>

        [autofit] Remove some styles.

        * src/autofit/afcover.h: Remove coverages for alternative fractions,
        denominators, numerators, and fractions.

        * src/autofit/afstyles.h (META_STYLE_LATIN): Updated.

2014-01-01  Werner Lemberg  <wl@gnu.org>

        [autofit] Add more styles.

        * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New
        auxiliary macros; use them to define styles for Cyrillic, Greek, and
        Latin.

        * src/autofit/afcover.h: Remove coverage for oldstyle figures.
        Since those digits are used in combination with ordinary letters, it
        makes no sense to handle them separately.

        * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
        `options' parameter to 4 bits.

2014-01-01  Werner Lemberg  <wl@gnu.org>

        * src/autofit/hbshim.c (af_get_coverage)
        [FT_CONFIG_OPTION_USE_HARFBUZZ]: Scan GPOS coverage of features also
        so that we can skip glyphs that have both GSUB and GPOS data.

        * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.

2014-01-01  Werner Lemberg  <wl@gnu.org>

        Redefine to construct HarfBuzz features.
        (af_get_char_index) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Rewritten.

        Add argument for y offset (to be used in a yet-to-come patch).

        src/autofit/aflatin.c: Updated.

2013-12-30  Werner Lemberg  <wl@gnu.org>

        [autofit] Don't combine multiple features into one set.

        Combining them, as originally envisioned, would lead to much more
        complicated code, as investigations have shown meanwhile.  The major
        drawback is that we run out of available style slots much earlier.
        However, this is only a theoretical issue since we don't support a
        large number of scripts currently.

        * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with
        a single-element `COVERAGE' macro, sort the elements by the feature
        tags, and add entry for `ruby'.

        * src/autofit/aftypes.h: Updated.
        * src/autofit/hbshim.c: Updated.

        [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function.

        * src/autofit/hbshim.h: Provide function declarations
        unconditionally.

2013-12-28  Werner Lemberg  <wl@gnu.org>

        [autofit] Add wrapper function for `FT_Get_Char_Index'.

        Yet-to-come changes will provide HarfBuzz functionality for the new
        function.

        * src/autofit/hbshim.c (af_get_char_index): New function.
        * src/autofit/hbshim.h: Updated.

        af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

        * src/autofit/aflatin.c (af_latin_metrics_init_widths,

        Updated.

2013-12-28  Werner Lemberg  <wl@gnu.org>

        [autofit] Use `global' HarfBuzz font object.

        We now use `hb_font' instead of `hb_face' since yet-to-come changes
        need this.

        * src/autofit/afglobal.h: Include `hbshim.h'.
        (AF_FaceGlobalsRec) [FT_CONFIG_OPTION_USE_HARFBUZZ]: New member
        `hb_font'.

        * src/autofit/afglobal.c (af_face_globals_new)
        [FT_CONFIG_OPTION_USE_HARFBUZZ]: Create `hb_font'.
        (af_face_globals_free) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Destroy
        `hb_font'.

        * src/autofit/hbshim.h: Include HarfBuzz headers.

        * src/autofit/hbshim.c: Include `hbshim.h' instead of HarfBuzz
        headers.

2013-12-27  Werner Lemberg  <wl@gnu.org>

        [autofit] Handle `DFLT' OpenType script for coverages.

        * include/ftautoh.h: Document new `default-script' property.

        [ftrfork] Fix the face order difference between POSIX and Carbon.

        The fragmented resources in Suitcase and .dfont should be reordered
        when `POST' resource for Type1 is being restored, but reordering of
        sfnt resources induces the different face order.  Now the ordering
        is restricted to `POST' resource only, to prevent the different
        order issue (e.g. the face index in the fontconfig cache generated
        with Carbon framework is incompatible with that by FreeType 2
        without Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

2013-12-21  Werner Lemberg  <wl@gnu.org>

        [autofit] Introduce `coverages'.

        Coverages are the interface to the HarfBuzz library to acces
        OpenType features for handling glyphs not addressable by the cmap.

        Right now, compilation of HarfBuzz is only added to the development
        build.  A solution for standard build mode will be delayed until
        HarfBuzz gets split into two libraries to avoid mutual dependencies
        between FreeType and HarfBuzz.

        Note that this is only a first step in handling coverages, basically
        providing the framework only.  Code for handling selected OpenType
        features (this is, actually using the data in `afcover.h') will
        follow.

        * devel/ftoption.h, include/config/ftoption.h

        (AF_DEFINE_STYLE_CLASS): Updated.

        * include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage
        data.

        * src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros.

        function name correctly corresponds to what the macro framework
        expects.

        * src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so

        Problem reported by David Kastrup <dak@gnu.org>.

        Surprisingly, a description how to do that was completely missing in
        the API reference.

        * include/freetype.h, include/ftchapters.h: New documentation
        section `header_inclusion'.

        [truetype] Fix positioning of composite glyphs.
        Problem reported by Nigel Tao <nigeltao@golang.org>.

        * src/truetype/ttgload.c (TT_Hint_Glyph): Remove code that shifts
        the glyph (component) by a fractional value computed from the LSB
        phantom point.  This is wrong, since the horizontal phantom points
        get rounded horizontally later on.

        [truetype] Next round in phantom point handling.

        Greg Hitchcock provided very interesting insights into the
        complicated history of the horizontal positions of the TSB and BSB
        phantom points.

        * src/truetype/ttgload.c (TT_LOADER_SET_PP)
        [TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and
        `grayscale_hinting' flags as conditionals for the x position of TSB
        and BSB.

2013-12-05  Werner Lemberg  <wl@gnu.org>

2013-12-03  Werner Lemberg  <wl@gnu.org>

        [truetype] Fix phantom point handling.

        This is a further improvement to the changes from 2013-11-06.

        * src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
        are rounded horizontally, vertical ones are rounded vertically.
        (TT_LOADER_SET_PP): The horizontal position of vertical phantom
        points in pre-ClearType mode is zero, as shown in the OpenType
        specification.

2013-12-02  Werner Lemberg  <wl@gnu.org>

        [truetype] Fix change from 2013-11-20.

        Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.

        * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
        `Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
        `IS_HINTED' clause.
        Also remove redundant check using `maxSizeOfInstructions' – in
        simple glyphs, the bytecode data comes before the outline data, and
        a validity test for this is already present.

2013-11-13  Werner Lemberg  <wl@gnu.org>

        Simplify header file hierarchy.

        This large patch changes the header file directory layout from
        `include/freetype/...' to `include/...', effectively removing one
        level.  Since the file `ft2build.h' is also located in `include'
        (and it stays there even after installation), all FreeType header
        files are now in a single directory.

        Applications that use (a) `freetype-config' or FreeType's
        `pkg-config' file to get the include directory for the compiler, and
        (b) the documented way for header inclusion like

          #include <ft2build.h>
          #include FT_FREETYPE_H
          ...

        * CMakeList.txt: Simplify.
        * builds/unix/freetype-config.in, builds/unix/freetype2.in: For
        `--cflags', return a single directory.
        * builds/unix/install.mk (install): No longer try to remove `cache'
        and `internal' subdirectories; instead, remove the `freetype'
        subdirectory.

        Problem reported by Nigel Tao <nigeltao@golang.org>.

        This is a follow-up commit to the previous one.

2013-11-06  Werner Lemberg  <wl@gnu.org>

        [truetype] Improve emulation of vertical metrics.

        This commit also improves the start values of vertical phantom
        points.  Kudos to Greg Hitchcock for help.

        * src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass
        `yMax' value.  Replace code with fixed Microsoft definition.
        (tt_get_metrics): Updated.
        (TT_LOADER_SET_PP): Add explanation how to initialize phantom
        points, taken from both the OpenType specification and private
        communication with Greg (which will eventually be added to the
        standard).
        Fix horizontal position of `pp3' and `pp4'.

        [truetype] Minor code refactoring.

        Two benefits: The allocated FDEF (and IDEF) array gets slightly
        smaller, and the `ttdebug' demo program has access to function
        numbers without additional costs.

        Fortunately, no changes to FontForge are necessary – this is the
        only external TrueType debugger I know of, but others may exist and
        should check the code accordingly.

        * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and
        `Cur_End' with a pointer to the corresponding `TT_DefRecord'
        structure.

        * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,

        shouldn't be any ABI problems.

        [arm] Fix thumb2 inline assembly under LLVM.

        When using `ADD' with an immediate operand, the instruction is
        actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
        immediate operand cannot exceed 4095.  It will fail to compile with
        LLVM.

        However, in GCC, due to some legacy compatibility considerations,
        `ADD.W' will be automatically emitted when the immediate operand is
        larger than 4095.

        * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.

        Note that the old code avoided using a region of the piecewise
        linear function where the slope was zero.  The recovery was to use a
        different section of the function, which produced a different,
        incorrect amount of darkening.

        * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.

        This line was lost in commit 89ca1fd6 (from 2013-06-25).  The effect
        is to use a previous darkening amount when producing an unhinted,
        unscaled outline.  This can cause autohint samples in ftgrid and
        ftview to be based on darkened CFF outlines instead of unhinted,
        undarkened ones.

2013-09-29  Dave Arnold  <darnold@adobe.com>

        Fix Savannah bug #39295.

        The bug was caused by switching to the initial hintmap (the one in
        effect when `moveto' executes) just before drawing the final element
        in the charstring.  This ensured that the path was closed (in both
        Character Space and Device Space).  But if the final element was a
        curve and if the final hintmap was different enough from the initial
        one, then the curve was visibly distorted.

        The first part of the fix is to draw the final curve using the final
        hintmap as specified by the charstring.  This corrects the
        distortion but does not ensure closing in Device Space.  It may
        require the rasterizer to automatically generate an extra closing
        line.  Depending on the hintmap differences, this line could be from
        zero to a couple pixels in length.

        The second part of the fix covers the case where the charstring
        subpath is closed with an explicit line.  We now modify that line's
        end point to avoid the distortion.

        Some glyphs in the bug report font (TexGyreHeros-Regular) that show
        the change are:

          25ppem    S (98)
          24ppem    eight (52)
          25.5ppem  p (85)

        Curves at the *end* of a subpath are no longer distorted.  However,
        some of these glyphs have bad hint substitutions in the middle of a
        subpath, and these are not affected.

        The patch has been tested with a set of 106 fonts that shipped with
        Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
        Google Fonts.  There are 1.5 million glyphs, of which some 20k are
        changed with the fix.  A sampling of a few hundred of these changes
        have been examined more closely, and the changes look good (or at
        least acceptable).

        FT_Open_Face: Improve external stream handling.

        If the font's `clazz->init_face' function wants to swap to new
        stream, handling of whether original stream was external could
        result to either memory leak or double free.  Mark externality into

        Better tracing of loaded glyphs.

        Previously, the loading of a glyph was traced at level 4, if at all.
        With this change, all font loading routines emit a tracing message
        at level 1, making it easier to select tracing output (for example
        using F2_DEBUG="any:1 afhints:7 aflatin:7").

2013-08-25  Werner Lemberg  <wl@gnu.org>

        [autofit] Introduce data file for blue strings.

        The idea is to have a central file which gets processed by a Perl
        script to create proper `.c' and `.h' files using templates.  There
        are two other reasons to do that:

          . The data file should be easily readable.  We use UTF-8 encoding
            which then gets converted to single bytes.

          . Since the number of supported scripts will increase soon, the
            current usage of blue string arrays is a waste of space.  Using
            the Perl script it is possible to imitate jagged arrays,
            defining enumeration constants as offsets into the arrays.

        This commit only adds files without changing any functionality.

        * src/autofit/afblue.dat: New data file.
        * src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

        [autofit] Improve handling of `near' points.

        Points which are very near to each other are now marked as such.
        The `weak' flag is then computed by using the `in' vector of the
        first and the `out' vector of the last point of a group of near
        points.

        For example, this fixes the rendering of glyph `Oslash' in
        `Roboto-Thin.ttf'.

        * src/autofit/afhints.c (af_glyph_hints_reload): Introduce
        the heuristic value `near_limit' to decide whether the current point
        is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
        Store good `in' vector (of last non-near point) in
        `last_good_in_{x,y}' and use it as an argument to
        `ft_corner_is_flat' if necessary.

        [autofit] Introduce `writing systems'.

        This patch adds a new top level to the auto-hinter's script class
        hierarchy.  It defines `writing systems' which can contain multiple
        scripts.

        For example, the `latin' writing system (in file `aflatin.c') is
        able to support scripts like Latin, Cyrillic, Armenian, etc., which
        can be handled similarly.

        [autofit] Fix segment classification for blue zones.

                      o---------------o

        as round.  (`o' and `x' are on and off points, respectively).

        This is a major change which should improve the rendering results
        enormously for many TrueType fonts, especially in the range approx.

2013-07-16  David Turner  <digit@google.com>

        Speed up ARMv7 support.

        When building for ARMv7 with thumb2 instructions, the optimized
        `FT_MulFix_arm' assembly routine was not being used.

        The reason for this is in the `ftconfig.h' header, namely:

        - The assembly routine uses the `smull' instruction which is not
          available when generating Thumb-1 machine code.  It is available
          in Thumb-2 mode, though.

        - The header was written a long time ago before Thumb-2 became
          widely popular (e.g. with Android).  So it simply doesn't use the
          assembly routine if the `__thumb__' built-in macro is defined.

        - When compiling in Thumb-2 mode, the compiler will define both
          `__thumb__' and `__thumb2__'.

        By checking for `(__thumb2__ || !__thumb__)', we ensure that the
        assembly routine is only avoided when generating Thumb-1 code.

        Given that this is performance-sensitive function, this improves
        `ftbench' as follows on a Galaxy Nexus:

        Fix Savannah bug #39266.

        If memory allocations fail at certain points while opening a font,

        reference count is set to 1, a subsequent `FT_Done_Library' call
        would otherwise loop over `FT_Done_Face' 2^32 times before freeing
        the face.

        Apply fixes for cppcheck nitpicks.

          http://cppcheck.sourceforge.net/

        The call was (from the top-level of the FreeType tree):

          cppcheck --force \
                   --enable=all \
                   -I include \

                   -I include/freetype/internal/ \
                   . &> cppcheck.log

        Note that the current version heavily chokes on FreeType, delivering
        many wrong results.  I will report those issues to the cppcheck team
        so that a newer version gives improved results hopefully.

        */* Improve variable scopes.

        LIBPNG_LDFLAGS.

2013-05-23  Behdad Esfahbod  <behdad@google.com>

        Add support for color embedded bitmaps (eg. color emoji).

        A new load flag, FT_LOAD_COLOR, makes FreeType load color
        embedded-bitmaps, following this draft specification

          https://color-emoji.googlecode.com/git/specification/v1.html

        which defines two new SFNT tables, `CBDT' and `CBLC' (named and
        modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
        are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
        pre-multiplied sRGB images.  If PNG support is available, PNG color
        images as defined in the same proposed specification are supported
        also.

        Note that color bitmaps are converted to grayscale if client didn't
        ask for color.

        * builds/unix/configure.raw: Search for libpng.
        Add `--without-png' option.
