So thats why cairo works with with X. Cairo needs a windowing system. 
I was
thinking of making a window system running on opengl. It is more of a 
reimplementation
of Mark Thomas`s Y. It is very similar to x so it would be 
straightforward to "hack up" the
x backend or cairo to run on y.

cairo-back could then run on 'x derivative' and then 'x derivative' 
could then run on
fbdri. cairo does not even need to know it is using opengl or should 
it?.
