Carlos Garnacho dbfde95c5c clutter: Do not check redraw area for pointer repicks
This looks like a relic of glReadPixels-based picking, the pointer
might well be outside redrawn areas, yet still require a device
update (e.g. in order to reflect the actor layout changes in the
"clear area" info).

Instead, always update all devices that are inside the view after
relayouts, the tracking on the need for that update is now done
on each ClutterStageView, instead of globally in the ClutterStage.

This theoretically fixes situations where pointers might miss
updating their "clear area" after the actor tree changed.
