The gstreamer-cairo integration is supposed to move all operations on
video frames into OpenGL. And that includes drawing onto and integrating
with other GL toolkits. In particular, the current code includes a
proof-of-concept integration with ProjectM.

I suppose every GL backend would provide native GL windows to draw onto,
so that would be portable. But then, nobody has written the GL backends
for Windows and OS X yet, so I don't know. ;)
