Description of the bug

I'm using UVtools for pcb exposure. It's way too difficult to zoom in to a needed level with the mousewheel - it's either too big or too small, and it takes quite an effort to get into the right zoom level. Is there a way to make the mousewheel less sensitive?

How to reproduce

open any pcb, try to zoom in/out

Each zoom tick will increase zoom by 0.25x / 0.5x / 1x / 4x depending on your current zoom level.
Zoom sensibility comes from mouse (If you use a free scroll well style or a special software controlled mouse) and from system. Program just catch each tick event... A tick is when you fell the mouse wheel to "click" in each movement.

For me under linux I can easy use zoom with precision to whatever level.
This is either your mouse or system settings

Indeed, I tried it on another linux mint system, with a real mouse, and it worked just fine. I connected that mouse to my initial system - and it also worked fine. So, the problem is narrowed down to my touchpad (I use the same two-finger 'scroll' gesture to zoom in and out, that I use to scroll content in browsers). However, there are couple of points:

1. this gesture works just fine with other software (e.g. kicad, system interface) - the problem is just with UVtools.
2. i couldn't find anything related to trackpad in this regard in system settings.

so, may be, it has something to do with the underlying framework?
