Improve support for WGL4 encoded fonts.
* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
(ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,
ft_wgl_extra_glyph_name_offsets): New arrays.
(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
(ps_unicodes_init): Use them to add additional Unicode mappings.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).
* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results. This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.
* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.
Update all callers.
(cff_slot_load): Handling scaling of subfonts properly.
* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
(cff_parse_font_matrix): Use it.
* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.
* docs/CHANGES: Document it.
reported by Ding Li on 2008/03/28 on freetype-devel.
* src/base/cff/cffparse.c (power_tens): New array.
(cff_parse_real): Rewritten to introduce a fourth parameter which
returns the `scaling' of the real number so that we have no
precision loss. This is not used yet.
Update all callers.
(cff_parse_fixed_thousand): Replace with...
(cff_parse_fixed_scaled): This function. Update all callers.
and `scale_y' as obsolete since they aren't used.
* src/psaux/psobjs.c (t1_builder_init): Updated.
* src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as
obsolete since they aren't used.
* src/cff/cffgload.c (cff_builder_init): Updated.
targets).
* src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
which is crossed by a `goto'.
* src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
* include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
FT_IS_CID_KEYED): New macros.
* src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
maximum CID value in CID-keyed CFFs.
Handle FT_FACE_FLAG_CID_KEYED flag.
* docs/CHANGES: Document it.
Fix CFF font matrix calculation and improve precision.
* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
part is zero.
(cff_parse_font_matrix): Simplify computation of `units_per_em';
this prevents overflow also.
Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
* src/cid/cidriver.c: Include FT_SERVICE_CID_H.
(cid_get_ros): New function.
(cid_service_cid_info): New service structure.
(cid_services): Register it.
