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.
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.
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.
No need for two arguments.
* include/config/ftconfig.h, builds/unix/ftconfig.in,
builds/vms/ftconfig.h (TYPEOF): Updated.
* include/internal/ftobjs.h (FT_PAD_FLOOR, FT_PIX_FLOOR),
src/autofit/afwarp.h (AF_WARPER_FLOOR): Updated.
This is the only place in FreeType where this function was used.
* include/config/ftstdlib.h (ft_labs): Remove.
* src/cache/ftcimage.c (ftc_inode_weight): Replace `ft_labs' with
`FT_ABS'.
* include/internal/t1types.h (AFM_KernPairRec): Make indices
unsigned.
Update users.
(AFM_FontInfoRec): Make element counters unsigned.
Update users.
* src/psaux/afmparse.h (AFM_ValueRec): Add union member for unsigned
int.
* src/psaux/afmparse.c (afm_parse_track_kern, afm_parse_kern_pairs):
Reject negative values for number of kerning elements.
* src/type1/t1afm.c, src/tools/test_afm.c: Updated.
It's unused after the following commits:
[raster] Allocate render pool for mono rasterizer on the stack.
[raster] Remove 5-level gray AA mode from monochrome rasterizer.
The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
serve, which is, to adjust the pool size. But the pool is now
allocated on the stack on demand.
* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
It was off by default and couldn't be turned on at runtime. And the
smooth rasterizer superceded it over ten years ago. No point in
keeping. Comments suggested that it was there for compatibility
with FreeType 1.
550 lines down.
* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
RASTER_GRAY_LINES): Remove macros and all associated code.
(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
(black_TRaster): Remove `grays' and `gray_width'.
(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,
ft_black_render): Updated.
* src/raster/ftrend1.c (ft_raster1_render): Simplify code.
(ft_raster5_renderer_class): Removed.
