EllipseComp, EllipseView, PSEllipse - ellipse component subject, view, and PostScript external

       EllipseComp is a GraphicComp that defines an ellipse.  It uses an Ellipse graphic to store its  graphical
       attributes.  EllipseView is a GraphicView for displaying the ellipse.  PSEllipse is a PostScriptView that
       externalizes the subject's information in PostScript form.

EllipseComp(SF_Ellipse*=nil)
              The  constructor  takes  an  optional  stroked-filled  ellipse  that defines the attributes of the
              ellipse.

       SF_Ellipse*GetEllipse()
              Return the SF_Ellipse graphic that defines the ellipse's attributes.  GetEllipse is simply a  more
              specific form of the GetGraphic operation.

EllipseView(EllipseComp*=nil)
              Create an EllipseView, optionally supplying the subject.

       virtualvoidInterpret(Command*)
              EllipseView interprets AlignToGridCmd to align its center to the grid.

       virtualManipulator*CreateManipulator(Viewer*,Event&,Transformer*,Tool*)virtualvoidInterpretManipulator(Manipulator*)
              EllipseView  redefines  its  response  to manipulation with a GraphicCompTool.  The user clicks to
              specify the center of the ellipse and then drags to vary its axes.  The center and the  axes  will
              be constrained by gravity, if any.

       EllipseComp*GetEllipseComp()
              Return the subject.

       EllipseComp,   EllipseView,  PSEllipse  -  ellipse  component  subject,  view,  and  PostScript  external
       representation

PSEllipse(EllipseComp*=nil)
              Construct a PostScript external representation of the given subject, if any.
