As you may remember, I proposed a bunch of RandR changes to support
per-CRTC pixmaps and atomic mode setting operations a while back. With
hardware now commonly supporting multiple overlays, even that stuff
wouldn't suffice anymore.

Off the top of my head, we'd need to construct some Drawable that
represented each overlay, and then perform a PolySwapRegion operation to
synchronously update their contents from appropriate back buffers.

And they're not arranged so that a single region and source offset x/y
could be used?

I can imagine creating a SwapRectangles request, but I don't know that
it would be any better than simply executing multiple SwapRegion
requests.
