8dc8635874 [raster] Remove 5-level gray AA mode from monochrome rasterizer.
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smooth rasterizer superceded it over ten years ago.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.

747ae2c8aa [smooth] Allocate render pool for smooth rasterizer on the stack.
Instead of using the `render_pool' member of `FT_Library' that is
provided down to the rasterizer, completely ignore that and allocate
needed objects on the stack instead.

With this patch, rasterizing glyphs from different faces from
different threads doesn't crash in the smooth rasterizer.

531d463aed [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
Previously the code had stipulation for using a per-TT_Size exec
context if `size->debug' was true.  But there was no way that
`size->debug' could *ever* be true.  As such, the code was always
using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
This was, clearly, not threadsafe.

With this patch, loading glyphs from different faces from different
threads doesn't crash in the bytecode loader code.

* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
(TT_DriverRec): Remove `context' member.

* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove
`TT_ExecContext' code related to a global `TT_Driver' object.

(tt_driver_done): Don't remove `TT_ExecContext' object here but ...
(tt_size_done_bytecode): ... here.

(tt_driver_init): Don't create `TT_ExecContext' object here but ...
(tt_size_init_bytecode): ... here, only on demand.

* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
code.
(TT_New_Context): Remove `TT_ExecContext' code related to a global
`TT_Driver' object.

* src/truetype/ttinterp.h: Updated.

* src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated.

89bc8d4de7 [autofit] Allocate AF_Loader on the stack instead of AF_Module.
Stop sharing a global `AF_Loader'.  Allocate one on the stack during
glyph load.

Right now this results in about 25% slowdown, to be fixed in a
following commit.

With this patch loading glyphs from different faces from different
threads doesn't immediately crash in the autohinting loader code.

Bugs:

  https://bugzilla.redhat.com/show_bug.cgi?id=1164941

* src/autofit/afloader.c (af_loader_init): Pass
`AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments.
(af_loader_reset, af_loader_load_glyph): Also pass `loader' as
argument.
(af_loader_done): Use `AF_Loader' instead of `AF_Module' as
argument.

* src/autofit/afmodule.c (af_autofitter_init): Don't call
`af_loader_init'.
(af_autofitter_done): Don't call `af_loader_done'.
(af_autofitter_load_glyph): Use a local `AF_Loader' object.

* src/autofit/afloader.h: Include `afmodule.h'.
Update prototypes.
Move typedef for `AF_Module' to...

* src/autofit/afmodule.h: ... this place.
No longer include `afloader.h'.

51abdf6ffa [otvalid] Fix a naming convention conflicting with ftvalid.
Some prototypes in ftvalid.h use `valid' for the variables
typed as FT_Validator.  Their implementations in src/base/
ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.

Some macros in otvcommn.h assume the exist of the variable
`valid' typed as OTV_Validator in the caller.

Mixing these two conventions cause invalid pointer conversion
and unexpected SEGV in longjmp.  To prevent it, all variables
typed as OTV_Validator are renamed to `otvalid'.

* src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
* src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
