Having projective transform wouldn't allow for "true" 3D (no z-buffer,
you can only try painter's algorithm, but that is not completely
general), but it would allow most 3D-like effects.
Anyway, what problems do you have using the output of cairo as a texture?
As long as texture resolution is high enough and filtering is set up
correctly (in GL), the result should be good.
