* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
interface to retrieve glyph data for a SEAC, it be left to the
incremental interface callback to apply the encoding to raw
character index (as it was in the previous code).
This code replaces the debugging hook from the previous commit with
a better, more generic solution.
* include/ftautoh.h: Document it.
* src/autofit/afmodule.h (AF_ModuleRec)
[AF_CONFIG_OPTION_USE_WARPER]: Add `warping' field.
* src/autofit/afmodule.c (_af_debug_disable_warper): Remove.
(af_property_set, af_property_get, af_autofitter_init)
[AF_CONFIG_OPTION_USE_WARPER]: Handle `warping' option.
* src/autofit/afhints.h (AF_HINTS_DO_WARP): Remove use of the no
longer existing `_af_debug_disable_warper'.
* src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c
(af_latin_hints_init), src/autofit/aflatin2.c (af_latin2_hints_init)
[AF_CONFIG_OPTION_USE_WARPER]: Add `AF_SCALER_FLAG_NO_WARPER' to the
scaler flags if warping is off.
* src/autofit/aftypes.h: Updated.
* src/autofit/afmodule.c (_af_debug_disable_warper)
[FT_DEBUG_AUTOFIT]: New global variable.
* src/autofit/aftypes.h: Updated.
(AF_SCALER_FLAG_NO_WARPER): New macro (not actively used yet).
* src/autofit/afhints.h (AF_HINTS_DO_WARP): New macro.
* src/autofi/aflatin.c (af_latin_hints_apply)
[AF_CONFIG_OPTION_USE_WARPER]: Use `AF_HINTS_DO_WARP' to control use
of warper.
* src/autofit/afcjk.c (af_cjk_hints_init, af_cjk_hints_apply)
[AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'.
* src/autofit/aflatin2.c (af_latin2_hints_apply)
[AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'.
Problem reported by Behdad.
* src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case
separately.
* src/cff/cffgload.c (cff_slot_load): Use advance width and side
bearing values from `hmtx' table if present.
The interface to ftgrid was broken in the series of commits starting
with
[autofit] Allocate AF_Loader on the stack instead of AF_Module.
from 2015-01-14.
* src/autofit/afmodule.c (_af_debug_hints_rec) [FT_DEBUG_AUTOFIT]:
Use a global AF_GlyphHintsRec object for debugging.
(af_autofitter_done, af_autofitter_load_glyph): Updated.
* src/autofit/afloader.c (af_loader_init, af_loader_done): Updated.
This commit allows `num_coords' to be larger or smaller than the
number of available axes while selecting a design instance, either
ignoring excess data or using defaults if data is missing.
* src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design):
Implement it.
* src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design,
T1_Set_Var_Design): Ditto.
Under normal circumstances we are usually close to the desired range
of angle values, so that the remainder is not really necessary.
* src/base/fttrigon.c (FT_Angle_Diff): Use loops instead of remainder.
* src/autofit/aftypes.h (AF_ANGLE_DIFF): Ditto in the unused macro.
* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Correctly handle
single-element runs. Cf. glyph `Q' in Skia.ttf with weights larger
than the default.
Thanks to Titus Nemeth <tn@tntypography.eu> for guidance!
* src/autofit/afblue.dat: Add blue zone data for Arabic.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Arabic standard characters.
* src/autofit/afranges.c: Add Arabic data.
* src/autofit/afstyles.h: Add Arabic data.
* docs/CHANGES: Document it.
* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix return value
of `point_cnt' if two bytes are read.
Use a more vertical coding style.
(ft_var_readpackeddeltas): Use FT_UInt for `delta_cnt' parameter.
Use a more vertical coding style.
