--- Comment #10 from Peter Hutterer <peter.hutterer at who-t.net> ---
speed is *one* metric for palm detection, but doesn't apply in this case. Here
it's a simple timeout, not the movement speed itself. IOW if you move out of
the area quickly enough, we assume this was a real movement. This is needed
because large left<->right movements frequently start with a finger in the edge
area.

Palms often move around a bit but less so than a finger, hence the timeout - if
it stays within the edge for long enough we assume it's a palm.

There's room for improvement as usual, e.g. we should have a maximum motion
towards the center at which we should un-palm the touch again. But no-one's
found the time to work on that yet.

Also, it's always hard to compare to macos - the apple touchpads are *very*
good, if I'd have to write libinput so it only works for those life would be a
lot easier :)
