+
+2014-12-11 Werner Lemberg <wl@gnu.org>
+
+ * builds/toplevel.mk (dist): Use older POSIX standard for `tar'.
+
+ Apparently, BSD tar isn't capable yet of handling POSIX-1.2001
+ (contrary to GNU tar), so force the POSIX-1.1988 format.

+ [gxvalid] Fix a naming convention conflicting with ftvalid.
+
+ See previous changeset for otvalid.
+
+ * src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace

+2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [otvalid] Fix a naming convention conflicting with ftvalid.
+
+ Some prototypes in ftvalid.h use `valid' for the variables
+ typed as FT_Validator. Their implementations in src/base/
+ ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
+
+ Some macros in otvcommn.h assume the exist of the variable
+ `valid' typed as OTV_Validator in the caller.
+
+ Mixing these two conventions cause invalid pointer conversion
+ and unexpected SEGV in longjmp. To prevent it, all variables
+ typed as OTV_Validator are renamed to `otvalid'.
+
+ * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
+ * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
+ otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'
+ if it is typed as OTV_Validator.

+
+ Original patch is designed by Werner Lemberg. Extra part

+
+ [pcf] Fix Savannah bug #43774.
+
+ Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'
+ functions. Since the PCF format doesn't have an official
+ specification, we have to exactly follow these functions' behaviour.
+
+ The problem was unveiled with a patch from 2014-11-06, fixing issue
+ #43547.
+
+ * src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last
+ element. Instead, assign real size.

+2014-12-04 Dave Arnold <darnold@adobe.com>
+
+ [cff] Modify an FT_ASSERT.
+
+ * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah
+ bug #43661, the test font `...aspartam.otf' still triggers an
+ FT_ASSERT. Since hintmap still works with count==0, ...
+ (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to
+ suppress the assert.

+2014-12-03 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Better fix for conversion specifiers in debug messages.
+
+ Using `%ld' for pointer differences causes warnings on 32bit
+ platforms. The correct type would be (the relatively new) `%td',
+ however, this is missing on some important platforms.
+
+ This patch improves the change from 2014-11-28.
+
+ * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
+ pointer differences are always sufficiently small.
+ (af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
+ af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
+
+2014-12-03 Werner Lemberg <wl@gnu.org>
+
+ FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality.
+
+ All public FreeType enumeration and flag values are uppercase...
+
+ * include/tttables.h (FT_Sfnt_Tag): Implement it. For backwards
+ compatilibity, retain the old values as macros.
+
+ * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c
+ (get_sfnt_table): Updated.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ * include/*: Improve structure of documentation.
+
+ . Add and update many `<Order>' tags.
+ . Apply various documentation fixes.
+ . Remove details to deprecated (or never implemented) data.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Always handle `<Order>' section elements.
+
+ Previously, those elements were handled only for sections present in
+ a `<Sections>' chapter element.
+
+ * src/tools/docmaker/content.py (ContentProcessor::finish):
+ Implement it.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Properly handle empty rows in Synopsis.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
+ ` ' for empty fields.
+

+
+ [docmaker] Thinko.
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ Emit `/empty/' string for first element also.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Honour empty lines in `<Order>' section element.
+
+ This greatly improves the readability of the `Synopsis' links.
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ Insert string `/empty/' between items.
+
+ * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it
+ robust against nonexistent keys.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
+ empty <td> elements for `/empty/'.
+
+2014-12-02 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Ensure Python 3 compatibility.
+
+ * src/tools/docmaker/content.py (ContentProcessor::set_section,
+ ContentProcessor::finish): Replace `has_key' function with `in'
+ keyword.
+
+ * src/tools/docmaker/formatter.py (Formatter::__init__): Replace
+ sorting function with a key generator.
+ (Formatter::add_identifier): Replace `has_key' function with `in'
+ keyword.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote):
+ Replace `has_key' function with `in' keyword.

+ integer division.
+ s/<>/>/.
+
+ * src/tools/docmaker/utils.py: Import `itertools'.
+ (index_sort): Replaced by...
+ (index_key): ... this new key generator (doing exactly the same).
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Don't output a block multiple times.
+
+ This bug was hidden by not processing all lines of `<Order>' blocks.
+

+ out field names.

+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Allow empty lines in `<Order>' blocks.
+
+ Before this patch, the suggested order of entries stopped at the
+ first empty line.
+
+ Obviously, nobody noticed that this problem caused a much reduced
+ set of links in the `Synopsis' sections; in particular, the
+ `<Order>' blocks contain a lot of entries that wouldn't be listed
+ otherwise...
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ New function to iterate over all items.
+ (DocSection::process): Use it.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>

+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Provide higher-level markup and simplify HTML.
+
+ * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'
+ elements, use CSS descendants (of class `section') to format the
+ data.
+
+ Also remove reduntant <p> and <br> elements, replacing them with
+ proper CSS.
+
+ Globally reduce page width to 75%.
+
+ (block_header): Rename <div> class to `section'.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Add `top' links after blocks.
+
+ * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it.
+
+2014-11-29 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/docmaker/tohtml.py: Improve CSS for fields.
+
+ Make fields align horizontally relative to full line width.

+
+ * src/tools/docmaker/tohtml.py: Fix index and TOC templates.
+
+ This thinko was introduced 2014-11-27.
+
+2014-11-28 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Format field lists with CSS.
+
+ This also simplifies the inserted HTML code.
+
+ * src/tools/docmaker/tohtml.py
+ (HtmlFormatter::print_html_field_list): Do it.

+
+ [docmaker] Replace empty `<td>' with CSS.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do
+ it.
+
+2014-11-28 Werner Lemberg <wl@gnu.org>
+
+ [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'.
+
+ * src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'.
+ (source_*): Use `<div>'.
+ (HtmlFormatter::block_enter): s/<h4>/<h3>/.

+
+2014-11-27 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
+
+ For `Index' and `TOC' links, we now simply use the `text-align' CSS
+ property of `<td>' to enforce flush-left and flush-right,
+ eliminating the hack with an empty, full-width `<td>' element
+ inbetween.
+
+ The change also enforces the same (smaller) size for all index and
+ TOC links.
+
+2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(),

+ This starts a series of commits into the direction of generating

+
+ Don't cast cmap init function pointers to an incompatible type.
+
+ Without this patch, the number of parameters between declaration and

+ undefined behavior.
+
+ ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
+ 6.5.2.2 Function calls
+ 9 If the function is defined with a type that is not
+ compatible with the type (of the expression) pointed to by
+ the expression that denotes the called function, the
+ behavior is undefined.
+
+ On certain platforms (c -> js with emscripten) this causes
+ termination of execution or invalid calls because in the emscripten
+ implementation, function pointers of different types are stored in
+ different pointer arrays. Incorrect pointer type here results in
+ indexing of an incorrect array.

+ [autofit] Fix Savannah bug #42148.
+
+ The adaptation of the cjk auto-hinter module to blue stringsets in
+ 2013-08-25 had three severe bugs. Mea culpa.
+
+ 1. Contrary to the latin auto-hinter, characters for reference and
+ overshoot values of a blue zone are specified separately. Due to
+ the screwed-up change it didn't work at all.
+
+ 2. A boolean comparison was erroneously replaced with a cast,
+ causing invalid results with the `^' operator later on. The
+ visual artifact caused by this problem is the topic of the bug
+ report.
+
+ 3. Two flag values were inverted, causing incorrect assignment of
+ reference and overshoot values.
+
+ * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
+ syntax to have both reference and overshoot characters in a single
+ string. This is error #1.
+ Add extensive comments.
+
+ * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no

+
+ [autofit] Redesign the recognition algorithm of strong points.
+
+ In particular, local extrema without horizontal or vertical segments
+ are better recognized:
+
+ + A + D
+ \ /
+ \ /
+ \ /
+ \ /
+ \ + C
+ \ /
+ B +/
+
+ If the distances AB and CD are large, point B wasn't previously
+ detected as an extremum since the `ft_corner_is_flat' function
+ `swallowed' BC regardless of its direction, tagging point B as weak.
+ The next iteration started at B and made `ft_corner_is_flat' swallow
+ point C, tagging it as weak also, et voilà.
+
+ To improve that, another pass gets now performed before calling
+ `ft_corner_is_flat' to improve the `topology' of an outline: A
+ sequence of non-horizontal or non-vertical vectors that point into
+ the same quadrant are handled as a single, large vector.
+
+ Additionally, distances of near points are now accumulated, which
+ makes the auto-hinter handle them as if they were prepended to the
+ next non-near vector.
+
+ This generally improves the auto-hinter's rendering results.
+
+ * src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
+
+ * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag

+ [autofit] Improve scoring algorithm for identifying stems.
+
+ Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
+
+ The new algorithm takes care of the width of stems: If the distance
+ between two segments is larger than the largest stem width, the
+ demerits quickly increase for larger distances. This improves
+ hinting of slanted fonts (especially if the inner parts of serifs
+ have non-horizontal `shoulders'), avoiding false stem links.
+
