Hash :70281e0f Message :[truetype] Modify the graphics state management.
Instead of restoring persistent GS variables, we only save modifications
permitted by the CVT program. This reduces the context manipulations.
* src/truetype/ttobjs.h (TT_GraphicsState): Reorder fields.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep):
Do not alter the context.
* src/truetype/ttgload.c (TT_Hint_Glyph): Do not reset GS.
(tt_loader_init): Fix potential issue in 'instruct_control' handling.
* src/truetype/ttinterp.c (TT_Run_Context): Fully reset GS.
(TT_Load_Conext): Rearrange and remove the 'size' check, already
performed in FT_Load_Glyph.
(TT_Save_Context): Save only modifiable GS parts.
(tt_default_graphics_state): Updated.
* src/truetype/ttinterp.h (TT_Run_Context): Update signature.
