The are two changes to GtkLayout where I think only one is important. Before
calling gdk_window_move we need to unmap the GtkWidget and afterwards map it
again. The method/closure connected to the value_changed signal of adjustments
is private, so subclassing is not possible.

The approaches I saw where:
    -I don't know if it is possible but disconnect the gtk_layout_value_changed
closure and implement this inside webkit. The downside was that the secret of
moving the window is shared between Gtk+ and WebKit and I assumed this will be
error prone.
     -One could try to connect the value_changed signal twice. The first
closure would unmap the GtkWidget in case of static backgrounds and the other
one would map it again. I was not certain if I can gurantee to always be called
before the GtkLayout closure.

I think one shouldn't share secrets and I'm not certain the second approach
will work, this is why I decided to copy/fork GtkLayout. I need some
clarification regarding Frame, FrameView and FrameTree interaction so we might
end up with a completely different approach (will send an email).
