* The mask was not subdivided properly on splitting edges, which gave interesting but definitely wrong fractal-like borders around masks. * Edge splitting was only done where the mask was < 50%, with the reasoning that you can't do a 50% topology update. But this gives an ugly border in the mesh. The mask should already make the brush move the vertices only 50%, which means that topology updates will also happen less frequent, that should be enough.
