Problem reported by John Emmas <johne53@tiscali.co.uk>.
* include/freetype/fterrors.h: Fix inclusion guard so that
undefining either `FTERRORS_H_' or `__FTERRORS_H__' works as
expected.
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.
* src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights): Enable filter
in addition to setting weights.
(FT_Library_SetLcdFilter): Clean out FT_FORCE_LIGHT_LCD_FILTER and
FT_FORCE_LEGACY_LCD_FILTER.
* include/freetype/ftlcdfil.h: Documentation update.
Such macro names are reserved for both C and C++.
* src/cache/ftccache.h: s/_FTC_FACE_ID_HASH/FTC_FACE_ID_HASH/.
Update all callers.
(FTC_CACHE_LOOKUP_CMP): Replace `_XXX' with `XXX_'.
* src/cache/ftcmru.c (FTC_MRULIST_LOOKUP_CMP): Ditto.
Such macro names are reserved for both C and C++.
* include/freetype/ftimage.h, src/raster/ftraster.c,
src/smooth/ftgrays.c, src/smooth/ftgrays.h:
s/_STANDALONE_/STANDALONE_/.
* src/cff/cf2intrp.c (cf2_interpT2CharString) [cf2_cmdEXTENDEDNMBR,
default]: `|' is not guaranteed to be processed from left to right
by the compiler. However, the code repeatedly calls
`cf2_buf_readByte' to get the arguments to `|' ... Fix this.
This improves rendering of scripts like Bengali or Devanagari.
* src/autofit/afhints.c (af_axis_hints_new_edge): Add parameter to
pass top-to-bottom hinting flag. This makes the function sort edges
in descending vertical position.
* src/autofit/afhints.c: Updated.
* src/autofit/aflatin.c (af_latin_hints_compute_edges,
af_latin_hint_edges): Use `top_to_bottom_hinting' flag.
* src/autofit/afcjk.c (af_cjk_hints_compute_edges),
src/autofit/aflatin2.c (af_latin2_hints_compute_edges): Updated.
Right now, it does nothing.
* src/autofit/afscript.h: Add another parameter to `SCRIPT',
specifying hinting direction.
* src/autofit/afglobal.c, scr/autofit/afglobal.h,
src/autofit/afpic.c, src/autofit/afranges.h, src/autofit/afshaper.c,
src/autofit/aftypes.h: Extend `SCRIPT' definitions.
We now use a hash to map from subr indices to array elements holding
the subroutines, if necessary.
* include/freetype/internal/t1types.h: Include FT_INTERNAL_HASH_H.
(T1_FontRec): Add `subrs_hash' field.
* include/freetype/internal/psaux.h: Include FT_INTERNAL_HASH_H.
(T1_DecoderRec): Add `subrs_hash' field.
* src/type1/t1load.h (T1_LoaderRec): Add `subrs_hash' field.
* src/type1/t1driver.c: Include FT_INTERNAL_HASH_H.
(t1_ps_get_font_value) [PS_DICT_SUBR]: Look up hash if necessary.
* src/type1/t1load.c: Include FT_INTERNAL_HASH_H.
(parse_subrs): Use hash for subr indices that exceed the allocated
number of subr slots.
(t1_init_loader): Remove unnecessary code.

hashing.
