  // Still, the behavior of the BoundingObject is really strange.
  // One would think that writing "setGeometry(aGeometry3D)" here would do the job.
  // But apparently the boundingObject can only be handled correctly, when it's
  // indexBounds are from -1 to 1 in all axis (so it is only 2x2x2 Pixels big) and the spacing
  // specifies it's actual bounds. This behavior needs to be analyzed and maybe changed.
  // Check also BUG 11406
