I think I won't bother. I found a simple workaround,
which is to add a handler for size_allocate events
on the window (not the drawing area), and let it set
a global boolean to indicate that this happened and
prevent a double update of the drawing area by ignoring
the next expose_event.
We'll see if this still works with the next Gtk version
or not.
