And on that note: may I suggest we use a superellipse shape for the
brush? This one any shape between a perfect circle/an ellipse and a
perfect square/a rectangle.
You just get one more slider 'Roundness'.
Roundness 0 is perctly sharp edges, 1 is perfectly round. In-between is
kinda a rectangle with nicely rounded corners (nicely = C2 continuous,
not just C1 as arcs joined wioth straight lines would be).
A negative roundness then allows star shapes as well.
I have the implicit form of the equations as well, which would probably
be ideal for rendering a bitmap (with smooth edges) of such a brush.
