Implement accelerated EXA DownloadFromScreen hook.

x11perf -getimage numbers only increase by about 20-30% on my PowerBook with an
M9, but by about 100 times(!) with a PCIe X550. I suspect the former could
perform better with PCI as opposed to AGP transfers, which would also remove
the need to disable this by default with AGP.
