   /* An external support-library for the superview.library is called a
      "svoperator".
      Each svoperator has to contain a "SVP_OperatorNode" structure (as follows)
      in its Library-Header, which later will be READ and MODIFIED by
      the superview.library.
      Because the superview.library supports three different sorts
      of SVOperators at the time (internal, independent and external),
      there are three different types of this structure (might be more in
      the future), which can be identified via their "svp_OperatorType".
