Intel UXA Acceleration Performance

UXA wasn't faster than EXA when it came to the simple GtkCheckButton widget testing. The results were close but EXA was faster by about 4%.

The last 2D GTK test was with the GtkDrawingArea Pixbufs where using the GEM-powered UXA acceleration took nearly half the time it took EXA to complete the benchmarking task.

With JXRenderMark, which effectively stresses the X Render extension, using UXA allowed for 44% more operations per second at rectangles blended of 128 x 128 px.

The trapezoid composition of 256 x 256 px with JXRenderMark was marginally slower with the UMA Acceleration Architecture. EXA had averaged 47 operations per second where as UXA was at 45 operations per second.
