Sorry for the ignorance, but what particular information are you talking
about here?

Information dealing with generating glyphs from unicode characters and
positioning them:

According to the MacOS X docs NSFont has a bunch of methods for similar
purpose, see methods staring with positionOfGlyph: Couldn't these be used
to get the necessary information in the gui or am I missing something?

In theory, these might be able to do some of the work when laying out
glyphs, but I wouldn't count on it. Either way, they don't help in the
actual glyph generation (only(?) ligatures in western scripts; look at
the different examples of indic scripts for more advanced glyph

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.
