This command draws an arc, given it's center and radius, using the current Color.
This command will always draw a circular arc.
The arc is drawn clockwise. An angle of 0 degrees correspond to the geometric angle of 0 degrees (3 o'clock on a watch.)
The startAngle parameter is the starting angle (in degrees) where the arc begins. If the start angle is negative or >= 360, the start angle is treated as start angle modulo 360.
The sweepAngle parameter is the sweep angle (in degrees) measured clockwise. If the sweep angle is >= 360, then the circle is drawn completely. If the sweep angle is negative, the sweep angle is treated as sweep angle modulo 360
If the optional useCenter parameter is 0 (default) the center is not included in the arc. If useCenter is 1, the center of the circle in the arc is included forming a wedge.
The optional fill parameter indicates if the arc is to be filled. 0 = no fill, 1 = fill. The default is no fill.
