Always use fallback shaping for vertical fonts.

2006-08-15  Behdad Esfahbod  <behdad@gnome.org>

        * modules/basic/basic-fc.c (basic_engine_shape): Always use
        fallback shaping for vertical fonts.

        * pango/pango-context.c (get_shaper_and_font): Always use basic
        shaper for vertical items (east/west gravity).
