[gtkada] Gtk.Extra.Plot

[Manuel Op de Coul]

Oh no, I've really spent much time trying to get my plots
to work again and still I haven't succeeded. Lots of glib
assertion errors and warnings which I couldn't figure out.
Now I realize what happened from a post on the gtkextra list:

So the plots are completely broken under GtkAda 2.2 because
they aren't upgraded to gtk-2 yet? :-( :-(
