Loop annotation.
Renders a circle, ellipse or pseudo-spline, depending on number of points. In pseudo-spline mode, it also renders how the annotation would look without the currently active point. The pseudo-spline initially approximates the shape of the previous ellipse and tries to avoid intersecting itself. I strongly advise against inheriting from or otherwise trying to mess with the internals of this class.
