Description Matthias Wienand CLA 2015-09-03 09:18:10 EDT 
Scrolling with the mouse wheel should probably be encapsulated by an AbstractScrollGesture which can take care of assembling individual scroll events into one gesture, i.e. reporting the begin (first scroll event), intermediate steps (subsequent scroll events), and the end (no scroll event for X millis) of the scroll gesture.
Comment 1 Matthias Wienand CLA 2016-01-06 09:37:14 EST 
I implemented the AbstractScrollGesture as described in the initial comment. Accordingly, I adjusted the FXScrollTool, and AbstractOnScrollPolicy and its implementations. The scroll gesture abstraction allows to undo the actions of multiple scroll events at once. The code is published on the master branch, therefore, I resolve this ticket as fixed for 3.11.0M5.
