  Message : [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam

• 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.
