[Xorg-driver-geode] [PATCH 5/7] Fix the PictOpSrc rendering

[Huang, FrankR]

From: Frank Huang <frankr.huang at amd.com>

*Use the PictOpClear to make other non-blending region to be black
if the op is PictOpSrc.
*Use exaScratch.repeat and exaScratch.maskrepeat together instead of
exaScratch.repeat when the mask is not zero
