Hi,

This patch adds a XRender based GetSrcAreaStretch. A lot of work is
offloaded to X (less round trips are needed) and it can take advantage
of hardware acceleration. On Nvidia and AMD drivers blt performance
has improved by 20% in CrystalMark2004 while more optimizations can be
added later on.

Regards,
Roderick Colenbrander
