Ah yes it is in the postscript area of the source code.
/draw_circle % filled? radius thickness draw_circle
{
setlinewidth % f? r
currentpoint % f? r x0 y0
3 2 roll % f? x0 y0 r
dup 0 rmoveto
0 360 arc closepath
stroke_and_fill?
} bind def

`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.
