Paints a stroke through points (normalised coordinates) onto a copy of raster. Dabs are
spaced at most a quarter radius apart. Painting combines with max, so going over the same area
again never exceeds strength; erasing subtracts the dab, so erasing with the brush that
painted removes it completely, soft edges included.
