Note that of course, nothing will be happening if there's nothing to 
actually happen. If your objects aren't moving, etc, then Qt won't 
constantly have to redraw items, at most, it'll just be blitting from 
the widget backing store to the screen, but even that shouldn't happen 
here since we only have one topmost window, and no cursor moving around, 
etc.
