This isn't working on my system. It would be a more user friendly not
working with the attached patch.
If both nona and enblend have GPU support, would be possible to get nona
to render to a texture that enblend picks up? This would prevent copying
the image from video RAM to main RAM, encoding an image file, decoding
it again, then copying it back to VRAM.
