  //   to capture depth buffer, only colors (see QTBUG-65155)
  // - there are multiple post-processing passes that take rendered output
  //   of the scene, optionally apply effects (add shadows, ambient occlusion,
  //   eye dome lighting) and finally output to the given surface
  // - there may be also two more passes when 3D axis is shown - see Qgs3DAxis
