Well, looking closer I found prerequisites *are* used in gtk, e.g. in
GtkCellEditable. This allowed me to quickly verify that
g_type_interface_prerequisites does work. But I was a bit surprised to
see GtkCellEditable report GObject, GtkObject and GtkWidget as
prerequisites when only GtkWidget is explicitly added as a prerequisite.
Why is it necessary to add all supers of an instantiatable type to the
prerequisites when the type itself is added ? It looks a bit confusing
to list all three as prerequisites in the docs for GtkCellEditable and
manually removing redundant supers from the prerequisites in gtk-doc
does not sound like the right solution...
