[vtkusers] BUG in vtkLeaderActor2D? - not!

[dean.inglis at camris.ca]

not a bug, it works, one just has to make sure and
set the lable to NULL:

  #  Create the widget and its representation
  vtkAngleRepresentation2D rep
  rep SetHandleRepresentation handle
  rep InstantiateHandleRepresentation
  [ rep GetRay1 ] SetLabel 0  <-------------
  [ rep GetRay1 ] AutoLabelOn
