--- Comment #1 from Peter Hutterer <peter.hutterer at who-t.net> ---
CC-ing Hans, he added the 4mm threshold and he has access to a semi-mt device.

fwiw, the problem is not the gesture detection itself but rather the low
resolution on semi-mt touchpads when two fingers are down. That makes it harder
to guess the direction they're moving and thus harder to distinguish between
pinch and scroll. The main question here would be how to avoid false positives
when we bias towards two-finger scrolling.
