E (RandR): Reimplement "resizing other monitors" when a specific 

monitor gets resized, so that we update the visual layout
appropriately. Also, do not raise "monitor_moved" callback for every
little move, rather wait until the move is finished and raise the
callback once.

NB: The "monitor_moved" callback frequency may change in the future.
