What about letting ScrollAnimatorGtk handle the scrolling history and passing the computed inertia to ScrollAnimationKinetic when triggering inertial scrolling? This may help using the velocity values from the swipe gesture directly.

x and y (which should probably be named velocityX and velocityY) could (should?) be used to trigger inertial scrolling.</pre>
