Protocol for window previews/thumbnails

I think that it would be a good idea to have a standard, cross-compositor
protocol for getting previews/thumbnails of windows, similar to XComposite.

This protocol should be as fast as possible and use as little system
resources as possible. It should probably provide a handle to the native
window surface.

It will also be necessary to receive damage events on these surfaces. I
don't know if this should be included in this protocol or if this should be
a separate protocol?

Does anyone have any ideas on the best way to design such a protocol?

Thank you
