+An ellipse is just a variant of a circle, do we really need a separate class
+for them?
+
+We have a separate class for arcs, and those are circle variants too.
+
+Maybe. The ellipse (and elliptical arc) have two focii and a rotation angle.
+But there's no reason why those extras couldn't go into the Circle class as
+well.
+
+Actually, all that's needed are the two focii and radius...
