87c81f04	2015-08-30T10:35:21	[autofit] Make glyph style array use 16bit values. * include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use `FT_UShort' for `map' field. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage, af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h (af_get_coverage): Use FT_UShort for `glyph_styles' array. * src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to 16 bits. (AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.
b57bb11a	2015-02-19T10:44:18	[autofit] Fix signedness issues. * src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afglobal.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aflatin2.c, src/autofit/afwarp.c, src/autofit/hbshim.c: Apply.

d7f45943	2014-05-13T15:33:11	[autofit] Fix comment.
abb3fcac	2014-04-25T22:13:32	* src/autofit/hbshim.c: Partially revert commit from 2014-04-17. Using input glyph coverage data is simply wrong. Problem reported by Nikolaus Waxweiler <madigens@gmail.com> and Mantas Mikulėnas <grawity@gmail.com>.
8c7fb78b	2014-04-17T15:53:25	[autofit] More coverage fixes for complex scripts. * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage of GSUB lookups into output coverage. Otherwise, ligatures are not handled properly. Don't check blue zone characters for default coverage.
8b1f2a6c	2014-04-14T07:58:19	[autofit] Improve coverage handling. * src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs appearing in the GPOS table if we are processing the default coverage.
23367ff9	2014-03-17T07:33:14	Fix Savannah bug #41869. This works around a problem with HarfBuzz (<= 0.9.26), which doesn't validate glyph indices returned by `hb_ot_layout_lookup_collect_glyphs'. * src/autofit/hbshim.c (af_get_coverage): Guard `idx'. * docs/CHANGES: Updated.
05565366	2014-03-06T18:56:58	Fixes for compilation with C++. * src/autofit/hbshim.c (scripts): Change type to `hb_script_t'. (af_get_coverage): Updated. (COVERAGE): Add cast.
91c7a97b	2014-02-17T16:38:31	[autofit] Fix `make multi' compilation. * src/hbshim.c: Include `afglobal.h' and `aftypes.h'.
a3364001	2014-01-26T09:45:23	[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/autofit/aftypes.h: Update use of `SCRIPT' macro. (AF_ScriptClassRec): Add members to hold two more standard characters. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afglobal.c, src/autofit/afglobal.h, * src/autofit/afpic.c, src/autofit/afranges.h, src/autofit/hbshim.c: Update use of `SCRIPT' macro. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Scan two more standard characters.

1b5bc897	2014-01-03T18:33:24	[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.
f45749b0	2014-01-03T18:09:36	[autofit] Fix scaling of HarfBuzz shaping. * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM.
abb2f730	2014-01-01T08:00:16	[autofit] Fix style assignments to glyphs. * 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.
0950f3a5	2014-01-01T07:48:20	* src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.

(af_get_char_index) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Rewritten. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Use `y_offset' to adjust `best_y'.
c9d9947c	2013-12-31T08:16:57	[autofit] Fix interface of `af_get_char_index'. * src/autofit/hbshim.c (af_get_char_index): Return error value. Add argument for y offset (to be used in a yet-to-come patch). * src/autofit/hbshim.h, src/autofit/afcjk.c, src/autofit/aflatin.c: Updated.
44aa7e0a	2013-12-30T07:41:22	[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.
072dc45d	2013-12-28T12:26:21	[autofit] Code shuffling to reduce use of cpp macros. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Call `af_get_coverage' unconditionally. * src/autofit/autofit.c: Include `hbshim.c' unconditionally. * src/autofit/hbshim.c (af_get_coverage) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function. * src/autofit/hbshim.h: Provide function declarations unconditionally.
17af586e	2013-12-28T10:33:01	[autofit] Add wrapper function for `FT_Get_Char_Index'.

6af01a04	2013-12-28T08:55:24	[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. (af_get_coverage): Updated.

(script_tags): Add one more element.

(af_autofitter_init): Updated.
19241347	2013-12-21T21:31:38	Introduce `coverages'. Coverages are the interface to the HarfBuzz library to access 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 (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.

Update. * src/autofit/afmodule.h (AF_ModuleRec): s/fallback_script/fallback_style/. * src/autofit/afmodule.c (af_property_set): Adapt handling of `fallback-script' property to set a fallback style.
