     1 Relative mode testing
     2 =====================
     3 
     4 See test program at the bottom of this file.

     6 Initial tests:
     7 
     8  - When in relative mode, the mouse shouldn't be moveable outside of the window.
     9  - When the cursor is outside the window when relative mode is enabled, mouse
    10    clicks should not go to whatever app was under the cursor previously.
    11  - When alt/cmd-tabbing between a relative mode app and another app, clicks when
    12    in the relative mode app should also not go to whatever app was under the
    13    cursor previously.
