Smooth continuous scrolling in JavaFX

I have a MacBook Pro with a touch enabled trackpad. When I open a large
image with the Mac preview app I can let the image slide softly over the
screen with a two finger gesture. Now I would like to do the same inside
a JavaFX app but this doesn't seems to work. The image jumps in roughly
10 pixel increments which just looks ugly. I experimented with the
JavaFX gestures but I did not get it to move smoothly. The scroll events
are always delivered in very coarse intervals in contrast to the zoom
and rotation events where this works perfectly.
So I have the following questions here:
Is this behavior the same on all touch enabled platforms or is this a
Is there anything I can do to get more fine grained scroll events?
Why is there such a difference between the scroll and the other events
Is this a bug or a feature?
