2018-04-30Saner memory managment in cttfontdesc, part 1.Tom Sepez
A subsequent patch will tackle the ad-hoc ref counting, but we can tidy this before going down that hole. Decouple CTTFontDesc creation from face setting. Remove union and treat single-entry case as vector's first element. Pass unique_ptr to prove memory ownership.
