[Cuis-dev] Best way to draw arcs

[Jon Hylands]

I did a little test - turned off all the stepping (wantsSteps returns false
for all of them now).

With that little dashboard opened, I still get about 1 FPS dragging it
around. In the final version I won't be dragging it around, but if all
those fancy graphics come at a cost that makes them unusable, I'm probably
going to have to go back to regular squeak (where things don't look nearly
as nice, but dragging the fully live dashboard still happens at 30+ FPS).
