Circle clipping

clipCircle() devides a circle into intervals of angles representing arcs of the circle. When the circle is completely inside the clip rectangle an interval [0.0, 2 * M_PI] is returned.

Parameters:

clipRect Clip rectangle

center Center of the circle

radius Radius of the circle

Returns:

Arcs of the circle
