      THESE METHODS OUTSIDE OF THE RENDERING PROCESS All concrete
      subclasses must be able to render themselves. There are three key
      render methods in vtk and they correspond to three different points
      in the rendering cycle. Any given prop may implement one or more of
      these methods. The first method is intended for rendering all opaque
      geometry. The second method is intended for rendering all translucent
      geometry. Most volume rendering mappers draw their results during
      this second method. The last method is to render any 2D annotation or
      overlays. Each of these methods return an integer value indicating
      whether or not this render method was applied to this data. */
