[sfnt] Rewrite GPOS kerning support. (2/2)
The previous code had a fundamental flaw: it didn't validate the necessary
parts of the 'GPOS' table before accessing it, causing crashes with
malformed data (since `TT_CONFIG_OPTION_GPOS_KERNING` is off by default,
standard fuzzers don't catch these problems). Additionally, it did a lot of
parsing while accessing kerning data, making it rather slow.
The new implementation fixes this. After validation, offsets to the 'GPOS'
lookup subtables used in the 'kern' feature that correspond to 'simple'
kerning (i.e., similar to 'kern' table kerning) are stored in `TT_Face`;
this greatly simplifies and accelerates access to the kerning data.
Testing with font `SF-Pro.ttf` version '1.00', the validation time for the
'GPOS' table increases the start-up time of `FT_New_Face` by less than 1%,
while calls to `FT_Get_Kerning` become about 3.5 times faster.
* include/freetype/internal (gpos_kerning_available): Replace with...
(gpos_lookups_kerning, num_gpos_lookups_kerning): ... these new fields.
Update callers.
* src/ttgpos.c [TT_CONFIG_OPTION_GPOS_KERNING]: A new implementation.

|
* src/sfnt/ttkern.h (TT_FACE_HAS_KERNING): Remove macro.
Given that we also support (limited) 'GPOS' table kerning if
`TT_CONFIG_OPTION_GPOS_KERNING` is defined, the name of this macro is
misleading since it only is true for 'kern' table kerning.
* src/sfnt/sfobjs.c (sfn_load_face): Replace `TT_FACE_HAS_KERNING` with
plain code.

[truetype] Rework handling of rendering mode in bytecode.
This replaces a large number of confusing boolean constructs that
describe the target rendering mode in the execution context with
the straight mode variable. It might fix some hidden bugs when
FT_LOAD_TARGET_XXX were used as flags, which they are not.
The condition that triggers the CV program re-execution is simplified.
These events due the rendering mode change are rather rare and unexpected
and, therefore, should not be over-analyzed. In v40, all mode changes
now trigger the CV program. In v35, only switches to/from mono do.
* src/truetype/ttinterp.h (TT_ExecContext): Replace 'grayscale',
'grayscale_cleartype', 'subpixel_hinting_lean', and 'vertical_lcd_lean'
with the rendering 'mode'.
* src/truetype/ttinterp.c (Ins_GETINFO): Updated.
* src/truetype/ttgload.c (tt_loader_init): Replace 'prep' re-execution
trigger and update 'backward_compatibility' condition.

the twilight zone initiation from here...
(tt_size_run_prep): ... to this function, sho that it is always

[truetype] Streamline backward compatibility.
The 'backward_compatibility' is only set in v40: no need to check
the interpreter version again and again. In addition, we now track
IUP in its lower bits. After both IUPx and IUPy have been called,
'backward_compatibility' becomes equal to 0x7.
