    libbalsa: In popup-widget, special case GtkToolbar
    
    When the user right-clicks on a toolbar button, the GdkEvent coordinates
    are relative to the button. The root x-coordinate is relative to the
    toolbar, so we use that to position the popup, instead of the event x.
    
    The event y-coordinate is a few pixels off from y relative to the
    toolbar, and making the pointed-to rectangle 5x5 instead of 0x0 mostly
    fixes it. The root y-coordinate is way off, and it seems better to use
    the event y.
