Why are you saying "click" when we are talking about mouse wheel. The
wheel is not clicked when the user wants to scroll, the wheel is
turned.

??? That's about 100 pixels on a reasonably-sized frame. How can such
large values support "precision pixelwise scrolling"?
Are we talking about the same thing? I was asking about the smallest
values of the deltas reported in the mouse wheel-up and wheel-down
events when the user turns the wheel the smallest amount possible.
