
The length ratio of major to minor axis (R) must be in range ]0, 1]. It is used only if the
ellipse arc through the endpoints, the midpoint and the inclination of the axis are not
clearly defined. This is the case when both endpoints have the same distance to the
main axis. (Then both end points have the same distance to the minor axis, else there
isn't a ellipse through these points and the system replaces the ellipse with a straight
line.)

Note: Regard, that this object is a 2,5-D object, so the ellipse is always located
in the X/Y-plane. Ellipses in other space planes aren't supported.
