Feature + PATCH: support more video resolutions

This really isn't a bug, but I'm not sure where else to post the diff.

When prototyping, I like flexibility in selecting "gameplay resolutions." . Here's one way to get a larger selection of display resolutions.

It's fun to see what things look like running at 480x272 (native res of the Sony PSP). ;^)
