too fast and buggy on_scroll_up/down

[ralencode]

Describe the bug
when scrolling on widgets with a touchpad, scroll speed is too fast. its not a big issue with a volume widget, but that makes workspace scroll unusable. also, there is a bug: when you release touchpad, scroll makes one step down. so, when you, for example, scroll the volume to 100, it gets to 99. when from 99 to 50, it gets to 49 (if step is 1%)

To Reproduce
Steps to reproduce the behavior:
use my config, hyprland and touchpad. try to scroll on volume and workspace widgets

Expected behavior
scrolling is 2-5 times slower, but if you want to scroll faster, you.. scroll faster. maybe assume some distance to a step, like when scroll goes 10 pixels, do one step or something idk how scroll works but ig its possible to calculate scroll distance

System information:

• Distro: Arch Linux
• Compositor: latest Hyprland from official repository (0.45.0)
• Ironbar version: ironbar-git from aur (0.16.1-pre)

regular mouse works perfectly fine tho

[ToxicMushroom]

Can repro on sway

I'm just responding to the scroll event sent by GTK, which helpfully seems to work completely different on trackpad than mouse. Hopefully I can debounce the event or try and do something clever to improve the situation.
