Fix another cases where painting long brush strokes with small radius was slowed

down, this time by the operator properties getting converted to a string for
display in the info window.

With 1000+ stroke points this can get slow, and takes up too much space anyway,
so now it's (somewhat arbitrarily) limited to printing only 10 points.
