Yeah, hmm, I'm not sure.

Ok, I tested it. Its really nice - astonishing effect, minimal impact. It do 
has some bugs though: 

- try hovering the trashcan on kdesktop - whoops!

- you only want this overlay when you use the icon in the same size. I have 
  a smaller icon size, and the animated overlay is bigger - causing the 
  hovered item to move under my mouse pointer, eventually flickering 
  horribly and making it break the animation effect. 

also, I'm wondering if we really want to recreate the QMovie on every item 
during hovering. - it means reloading the file again from disk. It might be 
better to cache it in the IconView itself and delay destruct it after using 
(free it after 1 minute or so). it seems the people want a minimum inpact 
animation - so we should make it at least a bit efficient.
