Persistence of font names is definitely out of the scope of cairo; the 
cross-platform APIs are supposed to make 'toy' applications easy to build 
with 'real' applications using a higher level text layout API on top of 
cairo.  That higher level API will invoke OS-depedent font discovery 
routines and have to deal with font names on it's own.
