This essentially moves the Kannada script from the `Indic' hinter to
the `Latin' hinter.
* src/autofit/afblue.dat: Add blue zone data for Kannada.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Kannada standard characters and move
data out of AF_CONFIG_OPTION_INDIC block.
* src/autofit/afranges.c: Move Kannada data out of
AF_CONFIG_OPTION_INDIC block.
* src/autofit/afstyles.h: Update Kannada data; in particular, use
AF_WRITING_SYSTEM_LATIN.
We need this for backwards compatibility.
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.
(t1_done_loader, T1_Open_Face): Updated.
* src/type1/t1gload.c (T1_Compute_Max_Advance, T1_Get_Advances,
T1_Load_Glyph): Updated.
* src/type1/t1objs.c (T1_Face_Done): Updated.
* src/psaux/t1decode.c: Include FT_INTERNAL_HASH_H.
(t1_decoder_parse_charstrings) [op_callsubr]: Look up hash if
necessary.
* src/cid/cidgload.c (cid_load_glyph): Updated.
* src/base/fthash.c (hash_num_lookup, hash_num_compare): New
functions.
(ft_hash_init): Add argument to select between number and string
hashing.
(ft_hash_num_insert, ft_hash_num_lookup): New functions.
* include/freetype/internal/fthash.h: Updated.
* src/bdf/bdflib.c (_bdf_parse_start): Updated.
* include/freetype/internal/fthash.c (FT_Hash_LookupFunc,
FT_Hash_CompareFunc, FT_Hash_FreeFunc): New typedefs.
(FT_HashRec): Add `lookup', `compare', and `free' fields.
* src/base/fthash.c (hash_str_lookup, hash_str_compare,
hash_str_free): New functions.
(ft_hash_init): Set function pointers.
(hash_bucket, ft_hash_free): Use them.
We want to support both an integer and a string key later on.
* include/freetype/internal/fthash.h (FT_Hashkey): New union.
(FT_HashnodeRec): Updated.
(ft_hash_insert, ft_hash_lookup): Renamed to ...
(ft_hash_str_insert, ft_hash_str_lookup): ... this.
* src/base/fthash.c (hash_bucket): Updated.
