    tablet: scale the available pressure range into the pressure thresholds · d93feba1
    Peter Hutterer authored
    Pens that don't have a pressure offset (caused by a worn-out tip) still have
    basic pressure thresholds to avoid tip events when we're still a bit away from
    the tablet or barely touching it. That range is currently 5% of the pressure
    for tip down, 1% for tip up.
    
    This leaves us with 95% of the range and that needs to be scaled correctly,
    otherwise the bottom 5% happen before a tip event and are inaccessible where
    applications don't look at pressure before tip down.
