I might be missing something, but the backend should have two references 
to a font, one is the GSFontInfo subclass, which provides information to 
the front-end, and the second is the fontRef, which is really just a 
shortcut just for the backend, so it doesn't have to lookup it's own 
internal font references structure each time a font is set.
