[Mesa-dev] [PATCH 3/4] Mesa changes for adding OpenSWR

[Rowley, Timothy O]

Switching the default renderer to swr was part of our development so that we could get users to test our driver without accidentally forgetting to change the driver and ending up with llvmpipe.  I was thinking we might be able to leave that change in since swr isn’t in the default automake gallium driver list, but forgot that scons builds everything by default.  I’ll make that change and split this patch into the two pieces as requested.
