> This is a PoC for performance testing.  
> It contains commented out code in PopupWindow and ProgressIndicatorSkin and two tests are failing because of that.
> This code avoids registering two listeners (on Scene and on Window) for each and every Node to support the aforementioned classes.  The complete change should update these two classes to add their own listeners instead.
