Both Postscript and SVG have a built-in arc function capable of drawing an arc (or an entire circle).

Bézier 2-D curves can approximate a circle, but cannot create a mathematical exact circle (although an approximation using 4 points is so precise that it is practically indistinguishable from a circle)

Well I suppose it is actually postscript. So I had better look at the full source?

Where is the code that actually draws a circle stencil? I am interested to see if it is done with Bezier curve techniques and to study that. I could not seem to find it in the scm area.
