      let pathtracers use either backplate or environmental light or both · c08262b0

      The backplate is like standard rendering's background. It does not
      move with the camera and it does not affect the appearance of objects
      in the scene.
      
      The environmental map moves with the camera and affects the appearance
      of objects in the scene. It is like VTK's newer SkyBox, with material
      effects turned on.
      
      SetBackgroundMode let's you choose which behaviour, or both. The case
      of using neither (to get a translucent background) is setable but
      has not been proven out in practice yet.
      
      The environment mode controls (color, gradient, texture) have new
      methods on vtkRenderer but these have no effect on standard rendering.
      Likewise SkyBox mode is not respected by the pathtracer. Unifying both
      of these has yet to be done.
      
      The default for the pathtracer was changed to use backplate and disable
      environment lighting. This makes default object brightness similar
      to standard VTK.
