<pre>I've pushed a change to mesa which disables the compute paths for the video
compositor on nouveau (well, basically just enabled for AMD). Unfortunately it
was relying on AMD-specific features. We probably could have implemented these,
but the benefits are dubious, so I didn't want to bother...
This also seems to fix the assertion in libdrm, which is probably triggerable
in more general ways, but oh well.

gallium/vl: use compute preference for all multimedia, not just blit
The compute paths in vl are a bit AMD-specific. For example, they (on
nouveau), try to use a BGRX8 image format, which is not supported.
Fixing all this is probably possible, but since the compute paths aren't
in any way better, it's difficult to care.
