  // 1. no problems when away from the origin
  // 2. the positions on the scale are right even after panning
  // 3. rotating a panned plot does not make it move relative to the box
  // 4. the plot and box nicely stay 40 pixels away from the sides (textlabels aside), even when
  // tilted. FitToScene==true
  // 6. the plot remains nicely parallel with the box, no deformations there.
  // 7. clipping planes work (they are supposed to hide half the box)
