This would also be useful for the CUDA implementation in Wine Staging.
CUDA also allows accessing OpenGL and Direct3D buffers. So far it is
only implemented for OpenGL, but if there was an easy way to get the
OpenGL handles for a Direct3D object, it would be possible to implement
at least some of these functions:
