Softpipe has only sampler support. This has turned out to be not so trivial, so it's possible I missed something.

Marek,

You are awesome!  Thanks so much for implementing this!

Patches 1-7 look great:

I replied with a comment on patch 8, and am not planning on reviewing
patches 9-13 as I'm not familiar with Gallium.
