Applying a patch from Keith Whitwell: Adds some svga3dutil support for surface flags, and uses those flags in Bunnies to specify the static VB/IB usage of its buffers. This is the same behaviour we expect from well-behaved guest drivers, and it makes Bunnies a better tool for performance testing various host configurations.
