Comment #4: That is Android's touch prediction logic (and the relevant
un-prediction) which is very small -- never more than half a frame
predicted ahead. So the un-prediction at the end of a gesture is at most
one touch event. If Unity8 is doing fling velocity calculation on a
granularity of one event then it's probably Unity8 that needs fixing
more. That would also explain why Unity8 randomly gets the fling
velocity wrong (my finger is moving slowly but the scroll is flung
quickly on release).

Comment #3: What about this?
/usr/share/unity8/Components/ScrollCalculator.qml
/usr/share/unity8/Panel/PanelVelocityCalculator.qml
etc.
