                pango_attr_gravity_hint_new()

        * pango/pango-context.c (update_attr_iterator),
        (itemize_state_init), (itemize_state_add_character),
        (get_shaper_and_font), (itemize_state_update_for_new_run):
        Handle gravity and gravity_hint attributes.

        * pango/pango-utils.h:
        * pango/pango-utils.c:
        New public function:

                pango_parse_enum()

        * pango/pango-markup.c (span_parse_func): Parse gravity and
        gravity_hint attributes for <span>.  Optimize a bit.

        '_' differences when matching attribute names for <span>.

        (parse_gravity), (parse_gravity_hint), (parse_hinting),
        (parse_wrap): Use a generic parse_enum() that uses pango_parse_enum().
