uxa: Reuse in-flight bo
When we need to allocate a new bo for use as a gpu target, first check
if we can reuse a pixmap that has already been relocated into the
aperture as a temporary target, for instance a glyph mask or a clip mask.
Before:
backend test min(s) median(s) stddev.
xlib firefox-planet-gnome 50.568 50.873 0.30%
xcb firefox-planet-gnome 49.686 53.003 3.92%
xlib evolution 40.115 40.131 0.86%
xcb evolution 28.241 28.285 0.18%
After:
backend test min(s) median(s) stddev.
xlib firefox-planet-gnome 47.759 48.233 0.80%
xcb firefox-planet-gnome 48.611 48.657 0.87%
xlib evolution 38.954 38.991 0.05%
xcb evolution 26.561 26.654 0.19%
And even more dramatic improvements when using a font size larger than
the maximum size of the glyph cache:
xcb firefox-36-20090611: 1.79x speedup
xlib firefox-36-20090611: 1.74x speedup
xcb firefox-36-20090609: 1.62x speedup
xlib firefox-36-20090609: 1.59x speedup
