This would also be a great way to handle overscan for video playback,
allow the user to specify the screen size and position (like with the
GUI settings) and the software scaler could properly place the image
on their screen.

I'd also be interested to see how it fares against converting 720p to
1080p for all the new native 1080p displays coming out (mainly to see
if its worth using the software scaler over the internal scalers built
in to the tv's).
