The PtEllipse class draws an ellipse.
The bounding box of the ellipse, which determines its height and width, is defined by two points that you can specify in the Pt_ARG_POINTS resource. These points are relative to the widget's Pt_ARG_ORIGIN. For more information, see PtGraphic.
If you don't set these points, Pt_ARG_DIM determines the height and width (see PtWidget).
