swrast has some internal stuff to mitigate the statechange overhead (if
you haven't swrasted in a while, it replaces its function pointer with a
stub, and when you go to use it it notices that it's been stubbed out
and assumes all state has changed).  Because of that,
swrast_InvalidateState ended up being <.1% CPU usage.  It's tempting to
move it out even still, but I think if we do then we'd need to
_swrast_Wakeup anywhere that we call into swrast.
