Usage

 * Press the button.
 * First click in 3D view sets ellipse center. Second click sets the first radius and orientation of the ellipse. Third click sets the other radius and the start of the arc. The fourth click sets the end of the arc.
 * After the fourth click, the arc of ellipse is created, together with a set of construction geometry aligned to it (major diameter, minor diameter, two foci). The construction geometry can be manually deleted if not needed, and recreated later. See Internal Alignment Constraint and Sketcher Show Hide Internal Geometry.
 * Pressing or clicking the right mouse button cancels the function.
