--- Comment #3 from Peter Hutterer <peter.hutterer at who-t.net> ---
there's no drawback to discarding touches with very high pressure, it's
primarily the overlap area where it gets tricky. so yes, we could add something
that discards the palms over some device-specific threshold.

one of the problems we found in the past though was that the palms start with
normal pressure and don't reach maximum pressure until several events in. By
then we may have started gestures/scrolling/movement and it is very hard to
revert back and undo the state. this may be easier combined with the other palm
detection features where we just change from palm-maybe to palm-yes when the
pressure is detected.
