  35             This primitive encapsualtes a child hierarchy and defines
  36             that it shall be visualized with the given transparency. That
  37             transparency is unique for all contained geometry, so that
  38             e.g. overlapping polygons in the child geometry will not show
  39             regions of combined transparency, but be all rendered with the
  40             defined, single transparency.
