I created a game in 800x600 and I notice that when I turn on fullscreen this will stretch, thus distort, the window when on a widescreen(1280x800). I figure this might be what you would want, but I rather just stretch the window so that it fills the screen vertically, with black borders on the left and right. Is it possible to get this behavior with Gosu? If anybody has any suggestion or feedback it would be appreciated.

I'm running Ubuntu 8.04 and I don't know whether this behavior is platform specific or not.

This should happen on all Linux systems and on some Windows/Mac systems (depending on drivers).

I have rewritten the fullscreen code to make it much easier to fix such issues, and since it seems to work fine except for these stretching problems, I'll try my best to address this in the upcoming version (due before this weekend, for the Ludum Dare compo).
