I re-benched and I can confirm; context_apply_fbo_state() is no longer a 
significant bottleneck in the batch size tests.  However, this is a 
relatively recent change, in the past few weeks at most.  On the other 
3DMark06 tests that still do use offscreen rendering it's noticeable 
though, eg in HDR1/Canyon Flight it takes context_apply_fbo_state() from 
4.25% => 1.36% of wined3d.  Attached is the rebased version.
