The pertinent delta is the one for the axis whose value is larger. If
more scrolling has taken place on the X axis, then the relevant delta is
that for the Y axis. Otherwise, it is the delta for the Y axis.
If that delta is less than 0, a wheel-down event is produced.
Otherwise, a wheel-up event is produced instead.
>> . where and how are the PIXEL-DELTA data used for scrolling?
Only in pixel-scroll-precision-mode; the traditional mouse wheel
scrolling code derives the direction in which to scroll from the type of
the wheel event.
