Forward ScheduleOverlayPlane calls on Chromecast
Forward ScheduleOverlayPlane calls on Chromecast

This early-out case exists purely for Chromecast.  However, we
would actually like to continue and call ScheduleOverlayPlane on
the surface; this calls through to our CastPixmap::ScheduleOverlayPlane,
where we have some important logging that allows us to track use
of overlays in bug reports.
