Relative mode testing
=====================

See test program at the bottom of this file.

Initial tests:

 - When in relative mode, the mouse shouldn't be moveable outside of the window.
 - When the cursor is outside the window when relative mode is enabled, mouse
   clicks should not go to whatever app was under the cursor previously.
 - When alt/cmd-tabbing between a relative mode app and another app, clicks when
   in the relative mode app should also not go to whatever app was under the
   cursor previously.
