... which is similar to gimp_async_add_callback(), taking an
additional GObject argument. The object is kept alive for the
duration of the callback, and the callback is automatically removed
when the object is destroyed (if it hasn't been already called).
This is analogous to g_signal_connect_object(), compared to
g_signal_connect().
