* include/freetype/freetype.h, include/freetype/internal/ftgloadr.h,
|
||||
src/base/ftobjs.c: adding FT_Get_SubGlyph_Info API to retrieve subglyph
|
||||
data. Note that we do not expose FT_SubGlyphRec here !
|

|
||||
* src/autofit/afloader.c: compute lsb_delta and rsb_delta correctly
|
||||
in edge cases
