Basically, we need to expose not only whether or not the mouse wheel has
been scrolled, but exactly how much it has been scrolled, each time a
wheel event is sent.
We expose it to Lisp as the amount of pixels the text should be scrolled
in each axis, as that is the most common format used by modern window
systems.
Thanks.
