Arguments: stream center radius start-angle length-angle
Draws on stream a circle-sector, that is an arc and the bounding radii to produce a shape like a piece of pie, starting at start-angle and subtending length-angle, with the radius and center as specified.
center must be a position (see make-position).
stream should be a cg-stream.
Angles are measured clockwise starting from the positive x-axis (taking the center as the origin). Thus start-angle 0 is the due East point if the circle is thought of as a compass. Start-angle 0 and length-angle 90 draws the lower right quarter, now thinking of the circle as a pie.
See erase-circle-sector.
