System Information
Operating system: Linux-4.15.0-108-generic-x86_64-with-debian-buster-sid 64 Bits

Blender Version
Broken: version: 2.83.3, branch: master, commit date: 2020-07-22 06:01, hash: 353e5bd749
Worked: (newest version of Blender that worked as expected)

Short description of error
Using the touchpad of the Apple Magic Mouse 2 to scroll returns the event.value NOTHING instead of NORTH or SOUTH.

I'm attaching a blend file with a simple script to output input event.type and event.value to the terminal.

input_events.blend

Exact steps for others to reproduce the error

on MacOS with a Magic Mouse 2 open the attached blend file and run the script from the Scripting workspace
use the tough pad on the mouse to swipe up or down
the terminal will print TRACKPADPAN NOTHING
I'd expect it to print TRACKPADPAN NORTH or TRACKPADPAN SOUTH

These NORTH, SOUTH, ... these are for TWEAK events.

Trackpad events always event.val = KM_NOTHING.
Try to look at event.x, event.y, event.prevx, event.prevy.

There is no bug here.

These `NORTH`, `SOUTH`, ... these are for `TWEAK` events. Trackpad events always `event.val = KM_NOTHING`. Try to look at `event.x`, `event.y`, `event.prevx`, `event.prevy`. There is no bug here.

I suspected as much. I was hoping I could treat these trackpad events just like WHEELUPMOUSE and WHEELDOWNMOUSE, as single events, so I can fallback to use these if a mouse with scroll wheel is not available.
Comparing event.y with event.prev.y to determine the direction seems awkward, if at all possible. I don't actually want the trackpad to affect the mouse position.
