The ARC, Circle and Ellipse "built in" to MSWLogo will represent an ARC,
Circle or Ellipse as well any rasterized system can do.

Using SETPOS, SIN and COS you can do it as acurrately as the
built in version but slower. Turtle geometry does not have to be
ALL polar vectors. Turtle geomtry does both pretty well.
