public class OMEllipse
extends OMCircle

The OMEllipse is a lat/lon ellipse, made up of a center lat/lon point, and some length described for the x and y axis. If you want to create ellipses in X/Y space, use OMCircle. Ellipse arcs are not available yet, and this class doesn't really work with the EditableOMCircle. You can use EditableOMCircles to move and delete OMEllipses, but you can't change the axis dimensions.
