screen-cast: Only check queued-redraw on the relevant views

We'd check if there was any queued redraw on the stage, but this is
inappropriate for two reasons:

1) A monitor and area screen cast source only cares about damage on a
   subset of the stage.
2) The global pending-redraw is going away when paint scheduling will be
   more view centric.
