Looking good basically. I haven't noticed any correctness regressions,
but x11perf -aa10text seems to have dropped from almost 600k/s to just
above 500k/s. Haven't had time to really look into why that is, but one
thing I noticed before on kms-support is that we seem to be
(re-)emitting some 2D state we never use with EXA, e.g. background
colours. It might be worth even trying not to re-emit state that hasn't
changed.

I also pushed some warning fixes.
