A circular arc that is defined by a start point, end point, and a third point on the arc.
A circular arc-by-3-points where the start, end and intermediate point coincide represents an arc on a circle with these points as its center and a radius of 0.
A circular arc-by-3-points where 2 out of 3 points coincide represents an arc on a circle with its center located in the middle between the 2 coinciding points and the other point. If the start and end point coincide, a full circle is drawn, otherwise, the arc is interpreted as half a circle in counterclockwise direction from start to end point.
