        * pango/opentype/ftxgsub.c (Lookup_ContextSubst2,
        Lookup_ChainContextSubst2): Fix a couple of
        places where TTO_Err_Not_Covered wasn't considered
        a successful return from Get_Class -- it means
        use class index 0. (From FreeType, Werner Lemberg,
        2001-08-06)
