Input: wacom - add ABS_DISTANCE to Bamboo Pen reports
Tablet reports a distance of 0 right at highest point possible to be in proximity and distance_max when touching tablet. Inverse the distance since user land has no way of knowing ABS_DISTANCE is not distance from tablet. Signed-off-by: Chris Bagwell <chris@cnpbagwell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
