Animated items using delegates

A nasty hack involving a custom delegate, timer events and a signal to inform a view that it needs to repaint itself. It is just a proof of concept.

Perhaps a better example might be Animated items using delegates and movies.

Things that are wrong with this code:

It starts a timer and never stops it.
The signal in the delegate is connected to the viewport of the view instead of the view itself (it doesn't work otherwise).
The delegate simply shifts the normal content of the waiting items and paints a pixmap - it doesn't try to replace or add an icon to existing items.
