NAME
       GfxFree -- free a graphics extended data structure (V36)

   SYNOPSIS
       GfxFree( node );
              a0

        void GfxFree(struct extendednode *);

   FUNCTION
        Free a special graphics extended data structure (each of which
        begins with an extendednode structure).

   INPUTS
        node = pointer to a graphics extended data structure obtained via
               gfxnew().

   RESULT
        the node is deallocated from memory. graphics will disassociate
        this special graphics extended node from any associated data
        structures, if necessary, before freeing it (see gfxassociate()).

   BUGS
        an alert() will be called if you attempt to free any structure
        other than a graphics extended data structure obtained via GfxFree().
