Does A Greedy Intel Driver Improve Performance?

EXA performed roughly the same speed as UXA at transformed blit linear, but the greedy migration heuristics caused the performance to drop off with EXA.
UXA was much faster than EXA at the transformed blit bilinear test.
Continuing with JXRenderMark, at the linear gradient blend test the highest performance was found with the EXA greedy configuration. UXA was over twice as slow as EXA. The xf86-video-intel 2.6 driver with EXA was slightly slower than EXA on the 2.4 driver.
The performance between the four test settings led to similar performance at the radial gradient paint.
