Yes, now it nicely works for Pixel Brush. There is bug which leaves some 
pixels from the outline on the canvas til the time you somehow refresh the 
canvas  (turn on and off the layer visibility (eye icon))

I commited some code for deform brush. For deform brush I need just 
paint the circle with radius. If Cyrille could fix the code for the deform,
I would helped me much. I still don't know what I'm doing wrong.

I looked at KisBoundaryPainter::paint method but I don't get why it works 
there and does not work in deform brush.
