This was a quick solution to a problem.  It warrents a discussion, and I'll post
comments soon.

nak... this is not true on non-aura (FTM even on aura if --ui-use-gpu-process
isn't set).
Besides, the GPU side shouldn't have to know anything about the UI.

Yes, ideally incoming allocation hints are sufficient to prioritize allocations.
 Since we don't have those yet, I was hoping to ignore the UI, but that does
seem to be trouble.
