Remove the intermittent GEM_THROTTLE call.
This is a holdover from early GEM work when we weren't syncing on the
DRI client side. It would keep clients from getting too far ahead and
killing their interactivity, by bringing everyone to a halt when
anyone was too far ahead.
Now, GL clients throttle themselves to avoid the problem, and it turns
out that in the case that they don't (long rendering to buffers with
no swap), this actually reduces X Server interactivity: instead of
lagging of X rendering behind input, you get no response for seconds
at a time, then a burst of rendering, then nothing again.
Reported by ajax. Tested with moving a window while running
cairo-perf-trace on the GL backend (improvement) and X backend (no
significant change in responsiveness).
