Comment:
I tried to do this... I ran into problems.

`gtkglextmm` has a corresponding API to `gtkglext`'s `gtkglfont` api that needs to be killed off too.
Furthermore `ufoairadiant` breaks with this change as it has an internal library that links against `gtkglfont` for font rendering in `ufoairadiant`.
