draw-circle-arc

Arguments: stream center radius start-angle length-angle

Draws on stream a circle-arc, starting at start-angle and subtending length-angle, with the radius and center as specified.

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 arc from due East to due South. The endpoint coordinates may be determined by calling ellipse-start-and-end.

center should be a position (see make-position). stream should be a cg-stream.
