 DESCRIPTION
      This procedure is invoked to retrieve  an  option  from  the  database
      associated  with tkwin's main window.  If there is an option for tkwin
      that matches the given name or class, then it is returned in the  form
      of  a  Tk_Uid.   If  multiple  options  match name and class, then the
      highest-priority one is returned.  If no option matches, then NULL  is
      returned.

      Tk_GetOption caches options related to tkwin so that successive  calls
      for  the  same  tkwin  will  execute much more quickly than successive
      calls for different windows.
