This is a fine thing, gtk_window_set_size() in GTK 2 on an
already-visible window just does gdk_window_move_resize() basically.

However it isn't OK to do this in a show signal handler, I wouldn't
expect that to work so well. And even if it does it doesn't make any
kind of sense why you'd do it there.
