gestures: if fingers don't move, force a gesture by finger position
If the fingers rest on the touchpad without moving for a timeout, switch to
pinch or swipe based on the finger position. We already switched to two-finger
scrolling based on the timeout, now we also do so for 3 and 4 finger gestures.
This gives us better reaction to small movements.
This also fixes previously unreachable code: the test for the finger position
required at least 3 fingers down but was within a condition that ensured only
2 fingers were down. This was introduced in 11917061fe320c.
