They apply fine now, thanks. I'm afraid I can't really review them
beyond cosmetic issues though; Grigori, can you take a look?

Why do you think so?

At this point, glamor is on par with EXA in general, but there are cases
where it's significantly faster (many of which because EXA can't
accelerate them at all). Also, while glamor and Mesa are still being
actively developed, the xserver EXA code hasn't seen any significant
activity in years, i.e. it's basically dead or at least on life support.
