There was a lot of code here to do a lot of work we didn't need to do.
If we damage a surface with a shm buffer attached, all we need to do
is to re-upload the damaged region to the texture. As for drm buffers,
we don't assume anything changes on attach and only update the
regions the client tells us to update in the damage request.
This change depens on the Wayland core commit:
"protocol: remove absolute coordinates from pointer".
Remove the absolute coordinates from pointer motion and pointer_focus
events.
