Thanks for the clarification.  I guess I should maybe look at
caching the Cairo face then too, instead of (or in addition to)
the FT_Face I already have to cache...
Perhaps that'll help speed up the rendering of my PDFs too! :)
(Man some of these PDF viewers draw slow! :( )

I didn't know that - Thanks!

embedded user fonts, but I'll start a new thread when I get to that ]
