Good idea. :)

For KWin effects, the easiest way to integrate such a thing would be to have a 
method "valueAtTime()" like QTimeLine has it. Then we can probably port most 
effects rather easily. Right now, all animation progress is based on a single 
double, which is then used to calculate position, size and so on.

I'd love to see such a class that can then be extended with all kinds of curve 
types, it can probably also be used for plasma, although with a signal-based 
interface.
