hmm, then visibly, what I'm missing is something that actually work as you 
describe (I'd love to try it).

Problem is: it doesn't. I didn't made up the numbers, they are what's produced 
here when applying some simple instrumentation with the attached patch, and 
using the mouse wheel.

The result has changed slightly with your addition of today (I now see one 
slowing down step), but it still doesn't match you description at all:

setupSmoothScrolling: Smooth scrolling starting for  -80 vertical pixels
scrollTick: -14
scrollTick: -15
scrollTick: -14
scrollTick: -15
scrollTick: -14
scrollTick: -8
scrollTick: Elapsed:  85

Any idea what's wrong?
