Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkRenderPass.

Reimplemented in vtkEDLShading, vtkDepthOfFieldPass, vtkPointFillPass, vtkSimpleMotionBlurPass, and vtkFramebufferPass.
