Heh, do you mean GtkWindow widgets or GtkWidgets that have their own
GdkWindow ?

I think essentially to allow 0x0 allocations we either need to 
allow GdkWindows to be created at a 0x0 size (currently they
also force >= 1x1 internally)... or we need to add some special casing
code to GtkWidget's to handle their GdkWindows with care at
allocation time (naturally they all just call gdk_window_move_resize()
unconditionally).

Probably the former is better than the latter... even if the 
window has to do some hackery and hide itself when there is
a dimension of 0 size.
