Depending on the X server settings, certain modes aren't available in 
SDL.  In particular, on the default X install in Ubuntu on my system, 
there is not a mode to handle the standard console mode in Linux which 
means you get a centered console with large bars on the edges.  It's 
very ugly.

The mouse problem occurs less frequently in SDL because of the fact that 
you're always at native resolution (so the mouse moves around the screen 
almost as quickly as it normally would.  It's definitely reproducible.  
If you disable the mouse hiding in SDL mode, and you move the mouse 
slowly from one edge to another, you'll hit the box.

Probably.  I was hoping to punt on the issue of Win32 and instead rely 
on a native Win32 GUI.  I'm not sure GTK on Win32 is going to be that 
great from a performance perspective.

FWIW, I'm going to benchmark the my latest optimizations for fullscreen 
mode and post the results later today.  If scaling can be done with 
little performance impact, I think it's clearly the right thing to do.
