 * @class   vtkDisplaySizedImplicitPlaneRepresentation
 * @brief   a class defining the representation for a vtkDisplaySizedImplicitPlaneWidget
 *
 * This class is a concrete representation for the
 * vtkDisplaySizedImplicitPlaneWidget. It represents an display sized disk plane defined
 * by a normal and point. Through interaction with the widget, the plane can be manipulated
 * by adjusting the plane normal, disk radius or moving/picking the origin point.
 *
 * To use this representation, you normally define a (plane) origin and (plane)
 * normal. The PlaceWidget() method is also used to initially position the
 * representation.
 *
 * @warning
 * This class, and vtkDisplaySizedImplicitPlaneWidget, are next generation VTK
 * widgets.
