Hi Hans,
   The main difference is that the "size-request" signal/vfunc
implemented by widgets is replaced by a more elaborate
height for width interface for requesting sizes of widgets:
    http://library.gnome.org/devel/gtk/2.90/GtkSizeRequest.html

meaning in the end the whole requesting/allocating bit needs
to be reconsidered anyway.

Actually the GtkSizeRequestIface somehow broke the GtkWrapBox 
used internally in gimp iirc (with GTK+ git master I think its 
a toolbar that fails to wrap)... my hope is that this container 
can be a drop in replacement for these wrap boxes that might
be broken when running against GTK+ 3.0.

Cheers,
        -Tristan
