// .NAME vtkPVPartDisplay - Superclass for actor/mapper control.
// .SECTION Description
// This is a superclass for objects which display PVParts.
// vtkPVRenderModules create displays.  This class is not meant to be
// used directly, but it implements the simplest serial display
// which has no levels of detail.
