arc ( x_position, y_position, width, height, start_angle, width_angle )
arc center_x_position, center_y_position, radius, start_angle, width_angle
arc ( center_x_position, center_y_position, radius, start_angle, width_angle )

Draws an arc (part of a circle or ellipse) inside the rectangle defined by a bounding rectangle (defined by x_position, y_position, width, and height) or by a square bounding a circle (defined by center_x_position, center_y_position, radius). The angles are defined from the 12 o'clock position in a clockwise direction in radians.

Arc may also be used to draw an un-filled circle or an ellipse by defining the angular width to go all the way around (2*pi).
