Support (first font of) TTC files.

TTC is a TrueType Collection file (a collection of TTFs). Currently,ft2font only supports getting the first font from the collection, andneither the pdf nor ps backends are able to use them (due to limitationsof ttconv). Still, it seems better than nothing to support them for Aggand SVG (that comes for free via FreeType).
