/**
 * The GraphicUndefinedEditState is for a couple of OMGraphics that are still
 * undefined when they are created after a first click. We can have the
 * OMGraphic in an edit state, but we need to have a mouse released away from
 * the first mouse pressed in order to have an OMGraphic that makes sense. For
 * instance, circles and rectangles can't have just one point defined, so if
 * only one point is defined, the mouse dragged and mouse moved actions should
 * be the same, and then mouse release should mark the second definition point
 * of the OMGraphic.
