Enh. I've got dumb GPUs I need to support, they need to run OpenGL, and
if they were running swrast-on-otherwise-dumb-gem, I can make posting
the front buffer to the compositor be (at least sometimes) zero-copy,
instead of the XPutImage thing that drisw currently has to do. So I
don't think it's necessarily the case that swrast doesn't have
"hardware" support behind it.

More generally, if the term in the extension spec was "renderer" not
"device" I don't think we'd be having this discussion. And I think it's
worth having renderer selection be orthogonal in an API sense.
