That states the overlay has gone away.  I do know the Window Vista
eliminates the overlay programming model in lieu of compositing.  Other
graphics hardware will loose the overlay function in the future.

I don't know what the XV structure requires, but HW scaling is not limited
to overlay support.  It can be in a different place in the pipe.
