    gtk: Use 'emulating pointer' information when falling back
    
    We don't want to fallback for 'random' touch sequences, since
    that could lead to all kinds of pairedness and other violations.
    Since the X server already tells us what touch events it would
    have used for emulating pointer events, we just use that information
    here.
