commit e0eb855462791cbe217adc368d156733b2b2c13a

Detect standalone CFF fonts for FC_FONT_WRAPPER
FreeType will return CFF for both SFNT fonts with CFF table as well as
standalone CFF fonts, but applications might want to support the former
and not the later, so now FC_FONT_WRAPPER makes the distinction more
clear.
