    GtkWidget: Handle style updates before realize
    
    If the style changes before we're realized we will delay the
    style-updated signal until realize. However, we then lose
    the changes bitmap. This means that gtk_widget_real_style_updated()
    must treat a NULL change as "everything changed" and queue a resize.
    (cherry picked from commit 76e466197a5fef910ce76f76785829fa52d709e7)
