     fill_arc(+Drawable, +Gc, +X, +Y, +Width, +Height, +Theta1, +Theta2)

Draw a filled arc in Drawable. The arc is specified in terms of the rectangle that would enclose the ellipse of which this arec is a part, and the angles, in degrees from the center right of the ellipse, to draw between. X, Y, Width, and Height specify the bounding rectangle, Theta1 specifies the starting angle, and Theta2 specifies the ending angle. Angles may be integers or floats.
