branch: wl/sbix
commit 907715a6a214001db7504983f6cf2a48e8b33053
Author: Werner Lemberg <wl@gnu.org>
Commit: Werner Lemberg <wl@gnu.org>
Add `FT_FACE_FLAG_SBIX` and `FT_HAS_SBIX`.
Fonts with 'sbix' tables need special handling by the application.
* include/freetype/freetype.h (FT_FACE_FLAG_SBIX, FT_HAS_SBIX): New macros.
* src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix'
table is present.
