Smooth scrolling on linux

[RichardHladik]

Currently, ctrl.mouse_scroll(y=1, by_lines=False) scrolls by "one scrolling wheel revolution", and the by_lines parameter doesn't seem to do anything. I'd guess that the expected behavior is smooth scrolling, i.e., scrolling by 1px or something like that.
I am on arch linux, with xorg-server 1.20.11-1.

I'm not really sure how to simulate a smooth scroll event without uinput.

In theory you can use SendExtensionEvent with a ScrollClass from XI2
https://www.x.org/releases/X11R7.7/doc/inputproto/XI2proto.txt

But it didn't work in my basic testing. If someone gets SendEvent / SendExtensionEvent working with an XI2 smooth scrolling event, I will integrate it.

I'm interested in this feature, and willing to look into it.
What kind of testing didn't work? I assume this needs to be implemented inside Talon itself, so I am not sure what kind of PoC you'd need to consider this something you can integrate.

I would need example code that can simulate smooth scroll events over the X11 protocol. (I'm not interested in doing a uinput daemon yet).
