The alternative I've proposed is a function which you can call when you 
are "done" with the cairo_font_t object which guarantees that the FT_face 
will not be referenced again but doesn't destroy the cairo_font_t object.

I prefer this method both because it fits neatly into how I envision automatic 
memory management environments and also because it avoids callbacks from 
cairo with indeterminant threading liabilities.

It's clear that either will work for C usage.   It's also clear we could 
do both, but I'm sure most would agree that a single method would be 
preferred.
