New attribute types PANGO_ATTR_GRAVITY and PANGO_ATTR_GRAVITY_HINT. New

2007-01-16  Behdad Esfahbod  <behdad@gnome.org>

        * pango/pango-attributes.h:
        * pango/pango-attributes.c:
        New attribute types PANGO_ATTR_GRAVITY and PANGO_ATTR_GRAVITY_HINT.
        New public functions:

                pango_attr_gravity_new()
                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.

        * pango/pango-markup.c (parse_absolute_size), (attr_strcmp),
        (span_parse_int), (span_parse_boolean), (span_parse_color),
        (span_parse_enum), (span_parse_func): Use pango_scan_int(),
        pango_color_parse(), and pango_parse_enum().  Also, ignore '-' and
        '_' differences when matching attribute names for <span>.

        * examples/renderdemo.c (parse_enum), (parse_ellipsis),
        (parse_gravity), (parse_gravity_hint), (parse_hinting),
        (parse_wrap): Use a generic parse_enum() that uses pango_parse_enum().

        * modules/basic/basic-fc.c (basic_engine_shape):
        * pango/pangofc-fontmap.c (pango_fc_make_pattern):
        Use PANGO_GRAVITY_IS_VERTICAL().

        * pango/pango.def:
        * docs/pango-sections.txt:
        * docs/tmpl/text-attributes.sgml:
        * docs/tmpl/utils.sgml:
        Update.
