I give you the idea of what I have done. I added private member QImage m_img 
to KisQPainterCanvas and when the paint event is called with changed rect, the 
rect is painted to the QImage and then the rect is updated with other QPainter 
which is widget's one.

So we would not store one global QImage but allocate small ones per paint-
overlay action?
