        * pango/pango-renderer.[ch]: Remove color_set() virtual
        function ... it's not absolutely necessary for chaining
        renderers, and it's not clear that chaining renderers
        is actually useful, anyways.

        * pango/pango-renderer.[ch] (pango_renderer_set_color): Constify
        color argument.

        * pango/pango-render.c: Fix various bugs.

        * pango/pango-attributes.[ch] (pango_attr_shape_new_with_data):
        Add the ability to create a shape attribute with user data.

        * pango/pango-renderer.[ch] (PangoRendererClass): Add a draw_shape
        virtual function, to draw content for PangoAttrShape.

        * pango/pangoxft-fontmap.c (pango_xft_shutdown_display):
        Add note to docs that XCloseDisplay() will automatically take care
        of releasing Pango's allocated resources for the display.

        * docs/Makefile.am (SCAN_OPTIONS): Add the appropriate
        --deprecated-guards option.

        * docs/tmpl/xft-fonts.sgml: Add long description.

        * docs/tmpl/x-fonts.sgml: Document as dead.
