DESCRIPTION
       This procedure is invoked to retrieve an option from the database associated with tkwin's  main  win-dow. window.
       dow.   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.
