    app: extended device concept does not seem to exist in GTK+3.
    
    We were keeping around a flag telling us if coordinates are extended or
    not. In GTK+2, a device indeed had to be enabled. In GTK+3, I can see
    that device with extended inputs are enabled by default (they always
    have pressure, etc.). This flag is made useless.
