 ### The end animation

-game time the first thought was to have a self contained loop, using

+Instead the animation is handled by a QTimer, normally idle during play, 
+which once triggered repeatedly pings an 
+animation step-forward slot. This moves cards (faking 'gravity', bouncing)
 as well as re-stacking them once they're out of the play area. 
-Restacking uses the normal stacking code.

-The final step was to block event handling, otherwise the cards could
-still be grabbed while they bounced (and dropped). The easiest way to 
-achieve this was to simply place an event-capturing object over the entire
-window.
