+
+ [autofit] Fix handling of default script.
+
+ Patch taken from ttfautohint, commit
+ 071ae2c00e0d67f9d19418f4fade1c23d27dc185.
+
+ There were two bugs.
+
+ - We now use non-standard script tags like `khms' for special
+ purposes. However, HarfBuzz maps such tags to `DFLT', and
+ without this commit the associated lookups were incorrectly
+ assigned to the non-standard tags.
+
+ - Let's assume we have a Bengali font, and the font's `DFLT'
+ script tag handles the necessary lookups for Bengali, too.
+ Without this commit, the `DFLT' lookups were assigned to
+ ttfautohint's default script (usually `latn') before the
+ standard lookups for Bengali were handled.
+
+ We now have the following order while searching for covered
+ glyph indices.
+
+ special features of scripts (e.g. `sups' for Cyrillic)
+ Unicode mappings of scripts
+ remaining features of scripts (especially important for Indic
+ scripts)
+ default features of default script
+
+ * src/autofit/afshaper.c, src/autofit/afshaper.h
+ (af_shaper_get_coverage): Add boolean parameter to indicate default
+ script.
+ Update all callers.
+
+ * src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
+ Fix search order for coverages.

+ [autofit] Remove redundant code.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_widths): Do it.
+
+2015-12-09 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Thinko.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Don't count
+ empty blue zones (bug introduced 2015-12-06).
+
+2015-12-09 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Introduce subscript top blue zones.
+
+ This feature is mainly for Khmer: The idea is to avoid a clash
+ between the top of subscript glyphs and the bottom of normal
+ baseline glyphs.
+
+ This only works for character clusters mapped to multiple glyphs.
+
+ * src/autofit/afblue.dat: Add subscript top blue zone for Khmer.
+
+ * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New
+ macro.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE,
+ AF_LATIN_BLUE_SUB_TOP): New macros.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new
+ blue zone property.
+ Update tracing messages.
+ (af_latin_metrics_scale_dim): Handle new blue zone property.
+ (af_latin_hints_compute_blue_edges): Updated.
+
+2015-12-09 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fix tracing message.
+
+ * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Display
+ inactive blue zones also.
+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/afblue.dat: Add more Khmer clusters.
+
+ Some fonts have incorrect ligatures; we need more samples to get a
+ good mean value.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Typos.
+
+ * src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_get_elem)
+ [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Make it compile.
+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Add support for Khmer script.
+
+ We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
+ `Khmer symbols' (`khms', U+19E0-U+19FF).
+
+ * src/autofit/afblue.dat: Add blue zone data for Khmer.
+
+ * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+ * src/autofit/afscript.h: Add Khmer standard characters.
+
+ * src/autofit/afranges.c: Add Khmer data.
+
+ * src/autofit/afstyles.h: Add Khmer data.
+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Rewrite HarfBuzz interface to support character clusters.
+
+ Scripts like Khmer have blue zones that can't be directly
+ represented by Unicode characters. Instead, it is necessary to let
+ HarfBuzz convert character clusters into proper glyph representation
+ forms, then deriving the blue zone information from the resulting
+ glyphs.
+
+ * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
+ * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
+ files, providing a new API to access HarfBuzz.
+
+ The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
+ and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
+ string with function `af_shaper_get_cluster', and the resulting
+ glyph data (indices, advance widths, vertical offsets) can be
+ iteratively accessed with function `af_shaper_get_elem'.
+
+ * src/autofit/afcjk.c (af_cjk_metrics_init_widths,
+ af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_widths,
+ af_latin_metrics_init_blues, af_latin_metrics_check_digits):
+ Updated.
+
+ * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/.
+
+ * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.
+ (af_face_globals_compute_style_coverage): Updated.
+
+ * src/autofit/afglocal.h: s/hbshim.h/afshaper.h/.
+
+ * src/autofit/autofit.c: s/hbshim.c/afshaper.c/.
+
+ * src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC):
+ Updated.
+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Prepare forthcoming changes.
+
+ This makes it easier to control the commits.
+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy
+ loop. No functional change.
+
+2015-12-06 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Use string of standard characters.
+
+ This is more flexible; additionally, it would allow character
+ clusters.
+
+ * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
+ (AF_ScriptClassRec): Replace `standard_char[123]' with
+ `standard_charstring'.
+
+ * src/autofit/afscript.h: Replace last three character arguments
+ of the `SCRIPT' calls with a string parameter, holding the standard
+ characters (in UTF-8 encoding) separated with spaces.
+
+ * src/autofit/afglobal.c, src/autofit/afglobal.h,
+ src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c
+ (SCRIPT): Updated.
+
+ * src/autofit/afcjk.c (af_cjk_metrics_init_widths),
+ src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated.
+
+2015-12-05 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/afblue.dat: Separate blue zone characters with spaces.
+
+ Another preparation for character cluster support.
+
+ * src/autofit/afblue.c, src/autofit.afblue.h: Regenerated.
+
+2015-12-05 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces.
+
+ Instead, reduce multiple spaces to a single one. We need this later
+ for supporting character clusters in `afblue.dat'.
+
+2015-12-05 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/afblue.hin (GET_UTF8_CHAR): Use `do...while(0)'.
+
+ * src/autofit/afblue.h: Regenerated.

+
+ [type1] Avoid dangling pointer (#46572).
+
+ * src/type1/t1afm.c (T1_Read_Metrics): Properly reset
