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)
