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

Draws a pie shaped slice 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.
