i would suggest something like an extra NO_WINDOW container
(e.g. GtkSpaceBox ;) that will always request the size of its child, no
matter whether it is visible or not.
hm, come too think about it i belive i could hack that up pretty quick,
it should be a pretty small container derived from GtkBin that needs to
overload the size_request, size_allocate, map, unmap and expose handlers...
what do people think?

[owen, what leeman asks for is the current (visible!) behaviour if you force
unrealize a widget. (which would be bad since currently gtk_widget_unrealize
leaves GTK_MAPPED set on a widget that doesn't have a window anymore.)
do we have any possibility to prevent (preserve??) this visible behaviour,
without enforcing the invariants on gtk_widget_unrealize (which in turn
would change its behaviour)?]
