  // .NAME vtkPointsPainter - this painter paints verts.
  // .SECTION Description
  // This painter tries to paint points efficiently. Request to Render
  // any other primitive are ignored and not passed to the delegate painter,
  // if any. This painter cannot handle cell colors/normals. If they are
  // present the request is passed on to the Delegate painter. If this
  // class is able to render the primitive, the render request is not
  // propagated to the delegate painter.
