    ... and G_TYPE_INSTANCE_GET_PRIVATE()
    
    g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
    deprecated in GLib 2.58.  Instead, use
    G_DEFINE_TYPE_WITH_PRIVATE(), and G_ADD_PRIVATE(), and the
    implictly-defined foo_get_instance_private() functions, all of
    which are available in the GLib version we depend on.
