You're getting closer :-). 
If you look at the GIMP filters, they work with a dialog which displays a 
preview of the effect. So I think the image() method will be enough, maybe we 
can add a selection() method which would return a QRegion if we want to do 
more advanced stuff. I don't think we need mouse events.
