Stop coasting when two-finger scroll begins
There is currently a problem that can lead the coasting to continue while scrolling in a particular situation :
with
Option "VertTwoFingerScroll" "on"
Option "CornerCoasting" "0"
Option "CoastingSpeed" "10"
Option "CoastingFriction" "50"
Option "CornerCoasting" "0"
If you scroll down with two finger then raise a finger, coasting will start. But if you put down that finger and try to
scroll up, the inertia will still scroll down while you scroll up. This can look like a very particular situation, but
happens to me often while scrolling in a big document.
This (awfully simple) patch stop coasting when detecting two-finger scroll.
