Does A Greedy Intel Driver Improve Performance?

Greedy migration heuristics led to better performance with GtkDrawingArea Pixbufs. The Intel driver was nearly twice as fast when avoiding the non-greedy acceleration algorithms. The UXA performance continued to lag far behind.

Switching to the x11perf test, the 500px Put Image Square run had the best performance when using the default EXA acceleration on the 2.4 or 2.6 driver releases. The greedy migration heuristics were of little benefit here and the performance when using UXA had dropped sharply.

The EXA-based tests were able to perform about 250 operations per second at the Fill 300 x 300px AA Trapezoid test, but when using UXA that dropped to a mere 34 operations per second.

UXA performed better when dealing with 500px compositing from pixmap to window, but the greedy migration heuristics caused the driver to lose most of its speed. The old xf86-video-intel 2.4 driver with EXA was the fastest.
