As far as I know (correct me if I'm wrong!), [gemframebuffer] stores
images in GPU memory, you need to get it back to CPU memory as a pix,
using eg [pix_snap], but that only snaps what is currently displayed
(not from a framebuffer) (again correct me if I'm wrong).
And in my experience with oldish AGP graphics cards, GPU->CPU image
copying is rather slow. PCIe may be better, I don't know.
I don't know if there is any way to share GPU memory between independent
processes on the same machine, would be cool.
