There's my gst-plugins-cairo work which allows drawing to cairo-gl
surfaces using GL commands. I achieved that by adding the APIs
cairo_gl_surface_new_for_texture() and cairo_gl_surface_get_texture().
That way, I can take the surface's texture, create an FBO for it and
then draw to that FBO, or I can create a surface for my own texture and
draw that using traditional Cairo commands.
And of course, there's still the option of using a GLX window with Cairo
and draw to it with regular GL commands.

Does that sound like something that would work for you?
