Ah yes it is in the postscript area of the source code.
/draw_circle % filled? radius thickness draw_circle

Simple use of 360 degree arc. Answers what I wanted to know. There's a
lot of oldish webpages with complex Bezier curve constructions for
circles.Perhaps a version earlier than Postscript 3 did not have the arc
operator. Otherwise I don't know why you would bother.
Sorry for the noise.

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.
