[gtkada] Surprised by the changes to GTK 3.0

[Chris Sparks]

Thanks Emmanuel.

My problem is that I used the toolkit at a very low level (GDK). I did 
not use any of the GTK widgets or GLADE to generate my own personal 
widgets.  GDK really got altered.  Now I have to use Pango and Cairo 
which I didn't need to before and the interfaces to those are way 
different than what GDK had.
