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.
