[Xcb] XCB understanding in Mesa dri2

[Jamey Sharp]

You probably just want to look at the DRI2 protocol documentation,
because xcb-dri is only a small shim over that.

http://www.x.org/releases/X11R7.6/doc/dri2proto/dri2proto.txt

Specifically, I guess you want the DRI2CopyRegion request.

This list isn't a very good place to ask about what X requests like
that actually *do* though. We just know how to send them to an X
server and get replies back. You might try the xorg list instead:
