 Future work roadmap:
  * http://wiki.libsdl.org/moin.cgi/Roadmap
 
- * See why windows are being rearranged.  Is the shield window not up?
- * Add __WINDOWS__ in addition to __WIN32__
- * Write test for fullscreen gamma to check X11 colormap handling
-
  * Check 1.2 revisions:
 	3554 - Need to resolve semantics for locking keys on different platforms
 	4874 - Do we want screen rotation?  At what level?
 	4974 - Windows file code needs to convert UTF-8 to Unicode, but we don't need to tap dance for Windows 95/98
-	4484, 4485 - Verify that SDL's Windows keyboard handling works correctly
 	4865 - See if this is still needed (mouse coordinate clamping)
 	4866 - See if this is still needed (blocking window repositioning)
