Rocking!

Since no one else mentioned this in this thread IIRC, David Schleef has
been doing things like this, check his weblog:

Eventually when glimagesink gets updated there will be no need for
gldownload, the texture can be rendered directly.

There have been GPU-based filters before, and direct-path hardware
decoders, but not decoders on the GPU I don't think. You rock :-)

Cheers,
