// .NAME vtkRendererDelegate - Render the props of a vtkRenderer
// .SECTION Description
// vtkRendererDelegate is an abstract class with a pure virtual method Render.
// This method replaces the Render method of vtkRenderer to allow custom
// rendering from an external project. A RendererDelegate is connected to
// a vtkRenderer with method SetDelegate(). An external project just
// has to provide a concrete implementation of vtkRendererDelegate.
// .SECTION See Also
// vtkRenderer
