[cairo] Re: How to use Cairo glitz backend in existing FLTK OpenGL window?

[Bill Spitzak]

Can glitz be told to use an existing OpenGL context, or does it insist 
on creating it's own? Being able to use the existing current context 
would help a lot, in fact it would make this trivial. FLTK will swap the 
buffers for you and that is the only call that should be needed that 
needs the window id.
