I don't have the answer to your question, however I will point out
that gestures are hard to roll yourself because of "Switch Bounce".
That is, with my own two finger gesture, the number of finger contacts
is reported as 2,1,1,2,1,1,2,2,2,2,1,1,2 and so on. When just one
finger contact is reported, which of my two fingers is contacting
alternates randomly.
I'll be posting some "debounce" source but first I have to factor it
out from the rest of my app.
