New class KWidgetBlendAnimation

When I was going to adapt KWidgetBlendAnimation to the KDE global animation 
settings I suddenly saw that it is in kdelibs.

Nothing against this class, but there is a really important regression in the 
optimization part.

Try to maximize the phonon kcm, and make it switch. Or just try to apply the 
patch Urs wrote for KPageWidget, and change pages on config dialogs with the 
dialog maximized => extremely slow and lots of frame loss.

I had the same problem with previews on Open/Save dialogs, but those ones 
aren't expected to be that big, on the other hand I can maximize a dialog, 
what can be _really_ big.

I think before shipping and using this class widespread we should think twice 
about it. My desktop at least when windows are big (not huge, just big) feels 
really, really slow.
