[Xorg-driver-geode] PictOpOutReverse rendering issue

[Huang, FrankR]

Hi, all
	From my test in KDE environment, I found that there still one
new rendering bug.
	One example I post on:
		http://imagebin.ca/view/R3bCpQVU.html
	It is because of the PictOpOutReverse rendering with following
parameters:
	pSrc: PICT_a8r8g8b8  pMsk: PICT_a8 pDst:  PICT_a8r8g8b8
	That is very similar with PictOpOver condition. I am fixing that
now. If new findings from you, please feel free to report.
	Hope we can solve as much as the bug before new driver to
release.


Thanks,
Frank
