GTK_WIDGET_SET_FLAGS is "protected" API; also there is no way a GUI
builder would know what widgets you could toggle into 
no-window mode, and no way to express "set the NO_WINDOW flag" in 
GtkBuilder. And no notification or handling of it when the widget is
already realized.

There's a reason GtkFixed and GtkEventBox have API. (Why they don't have
the *same* API, I don't know...)
