  Message : Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.

• 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.
