- * We are really concerned about only three of the transition states [F = fullscreen, !F = floating]
- * F->!F, !F->!F, and !F->F. Each animation can only be cancelled from the target mid-transition,
- * or if a new animation starts on the same target.  The tests below verifies that the target is
- * notified of all the cases where it is animating and cancelled so that it can respond
- * appropriately.
