[Xorg-driver-geode] [PATCH 2/5] Put the one pixel rendering work back to the server to handle if the pMsk is not zero

[Huang, FrankR]

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

*With mask, our driver can only do one pixel source with repeat
rendering. That is a solid source picture. Otherwise, we must
return it to server.
