+ Singularily the most broken code in GTK is the code that is supposed to
inform subwindows (child windows) about new positions. Very often, duplicate
events are sent without changes in size or position, equally often no
events are sent at all (All this is due to a bug in the GtkContainer code
which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
GTK's own system and it simply waits for size events for toplevel windows
and then iterates down the respective size events to all window. This has
- the disadvantage, that windows might get size events before the GTK widget

and ending with the youngest generation (speaking of parent and child windows).
