So you use GtkFB? Cool. Does it work? Is it a commercial project?

I get very little feedback from people using GtkFB, so i have no idea if 
anyone is using it at all.

Isn't subfont_index 0 (glyph 0) only used for the unknown glyph? Were do 
you need this?

Anyway, I'll take a look at that problem. We do want to make the pango 
core handle aliases though (patch posted), and that would mean we could 
remove all the subfont stuff from modules (except for the core X fonts 
one).

We would also like to somehow integrate the different Freetype backends 
(Xft and Ft2) so that they can use common modules in some ways. We haven't 
really discussed this yet though.
