Draft: Improve handling of color palettes.
This commit adds new functions to streamline palette access:
- FT_Palette_Set: Set a user-defined palette.
- FT_Palette_Get: Get palette and palette index.
- FT_Palette_Get_Foreground_Color: Get foreground color.
Fixes issue #1134.
-
include/freetype/internal/tttypes.h (TT_FaceRec): Change type of

-
include/freetype/ftcolor.h: Updated.
