[[
The current Editor's draft includes the following formulas for 
converting wheel events to mousewheel and DOMMouseScroll events:

mousewheel.wheelDelta = -(WheelEvent.deltaY) / 120

DOMMouseScroll.detail = WheelEvent.deltaY / 3


Shouldn't those division signs be multiplication signs?  Everything I 
read says that IE returns a wheelDelta of +120 or -120 for a single 
wheel "click", and that Firefox returns a detail field of plus or minus 3.
