    tooltip: set window type hint for self-drawn tooltips to GDK_WINDOW_TYPE_HINT_TOOLTIP
    
    libcanberra generates specific tooltip popup sounds and for that
    recognizes the tooltip windows by the GtkWindowTypeHint set for them.
    
    This trivial patch simply sets the hint for the self-drawn tooltips
    metacity uses.
