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.
