xcb: Take advantage of clip-boxes
A demonstration of step 2, improves performance for selected benchmarks
on selected GPUs by up to 30%.
firefox-fishbowl on snb {i5-2520m): 42s -> 29s.
firefox-talos-gfx on snb: 7.6 -> 5.2s.
firefox-fishbowl on pnv (n450): 380 -> 360s.
Whist this looks like it is getting close to as good as we can achieve,
we are constrained by both our API and Xrender and fishbowl is about 50%
slower than peak performance (on snb).
And it fixes the older performance regression in firefox-planet-gnome.
