correctly treated as a CID, similar to FreeType's CID driver
module. Note that CID CMaps support is still missing.
- SFNT based fonts no longer set the FT_FACE_FLAGS_GLYPH_NAMES
flag if a version 3.0 `post' table is present.
- The FT_FACE_FLAGS_GLYPH_NAMES is now set correctly for all font
formats.
II. IMPORTANT CHANGES
