	Broadcast video.  Ever notice that the image on a standard TV channel
fills the entire TV screen?  Also, the actual satallite (broadcast) signal is
LARGER than what you see on the TV.

	This is quite a bit over the standard 640x200 resolution, which makes
overscan ideal for controlling the *entire* (or almost all) of the video
bandwidth you are mixing with your broadcast video (or whatever).

	Also... having an extra 60+ pixels horizontally and 60+ pixels 
vertically is *nice*.  For instance, full 80 column windows WITH BORDERS.
