        * test-display.c: (print_pixbuf), (save_svg), (main):
        * gdk-pixbuf-loader/io-svg.c: (fill_info):
        * gtk-engine/svg-render.c: (svg_cache_value_new):
        * rsvg-art-paint-server.c: (rsvg_art_paint_server_lin_grad_render),
        (rsvg_art_paint_server_rad_grad_render):
        Add more casts to quiet the gcc4 warnings. Some of these are
        particularly annoying and show the dangers of API functions that
        use unsigned char* for character strings. We now have casts for
        string literals (yuck\!). In a few places I was able to change the
        type of a buffer from char[] to unsigned char[] to avoid a cast.

        * doc/rsvg-sections.txt: Add all the unused declarations to this
        file in order to silence the compile-time warning. Most everything
        is added in a new Private subsection. Also add new rsvg-cairo
        block.
