If you submit a GTK+ documentation bug, and if someone says Yes, that is
a bug, then we might wrap this. You could back that bug up by pointing
them to the source of an existing application that does this.

We need to be very careful about wrapping private stuff - it could break
gtkmm's API/ABI if they change it later.
