Subject: [PATCH] AnimationGroup support and QGraphicsWidget* registration; one
 can now do things like:

l = new Label;
l.text = 'check this out'
fadeAnim = animation("fade")
fadeAnim.widgetToAnimate = l
rotateAnim = animation("rotate")
animGroup = new AnimationGroup
animGroup.parallel = true
animGroup.add(fadeAnim)
animGroup.add(rotateAnim)
animGroup.start()

and watch the label flip fade out while the whole plasmoid rotates. sweet.
