That parts need a little bit thinking. How do you plan on using the "shape", 
basically, what do you need in the API of KisBrush for your work ? Currently, 
KisBrush works by taking as argument the color (either a KoColor or a 
KisPaintDevice), some transformation (rotation + scale), then change the 
alpha channel of the KisPaintDevice and provide a dab that is then stamped on 
the canvas. I am not sure if it is a good solution for you ? (of course, the 
API can offer others solutions ;) )
