AFAICT, such check is not done. Neither in MediaPlayer's
VideoView::SetBitmap(), neither below.
The scale overlay restriction is purely ignored for the moment.
When in overlaymode, we could disable scales not supported in the
menu, or we could just fallback to drawing bitmap for scale out of
overlay limits.

+1
With graphic software issues, it's always easier to figure out what
happens when you can see the misbehavior instead of a blank screen (or
area for that matter).
