A follow-up from my previous post. So far, the only mention of this mouse wheel acceleration is in a article listed below: http://adomas.org/javascript-mouse-wheel/
Under Mac OS X the mouse wheel delta goes from -+0.1 to -+30.0 In XLib and Win32 API's, I could only get a delta of -+1 (no range). :-( Is the underlying windowing systems of XLib and Win32 to dumb to have a delta range? If so, what a pitty!
