Is there an easy way to make ScrollViewer resilient?

Question

Im using WPF ScrollViewer to host some controls. I would really like it to interact, as if on a touch device, where it slowly tidies up when you pull it too far.

It does not have a scrollbar - I have a manual mouse scroll with click and drag using this code:

Point currentPoint = e.GetPosition(this);

// Determine the new amount to scroll.
Point delta = new Point(scrollStartPoint.X - currentPoint.X, scrollStartPoint.Y - currentPoint.Y);

if (Math.Abs(delta.X) < PixelsToMoveToBeConsideredScroll &&
    Math.Abs(delta.Y) < PixelsToMoveToBeConsideredScroll)
    return;

scrollTarget.X = scrollStartOffset.X + delta.X;
scrollTarget.Y = scrollStartOffset.Y + delta.Y;

// Scroll to the new position.
sv.ScrollToHorizontalOffset(scrollTarget.X);
sv.ScrollToVerticalOffset(scrollTarget.Y);

Is there an easy way to do this? Currently, it just acts like a normal scroll text box and will not go beyond its normal range and not slow it down.
