Result: Minor diameter and foci are deleted, but the major diameter is kept, because it participates in other constraints. Ellipse's center remains too, because it is inherent, like center of a circle.
 * 1) Create a new ellipse. New ellipses are always fully-packed. You'll see an ellipse and a bunch of construction geometry: major diameter, minor diameter, foci.
 * 2) Select minor diameter line and hit . The diameter is gone, but the ellipse remains. How do we get the diameter back?
 * 3) Select the ellipse and invoke the  command. The diameter is restored.
 * 4) Now, constrain the major diameter of the ellipse to some length. Select the ellipse and invoke the  command.
