    (#596): Fix introspection data for rsvg_handle_set_stylesheet()
    
    Although the function's prototype changes:
    
     gboolean
     rsvg_handle_set_stylesheet (RsvgHandle  *handle,
    -                            const char  *css,
    +                            const guint8 *css,
                                 gsize        css_len,
                                 GError     **error)
    
    This is not an ABI break.  It is just to make clear that this is not a
    normal C string, but a buffer of bytes.
