DESCRIPTION
       This procedure is invoked to retrieve an option from the database asso-
       ciated 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.
