Mouse Wheel scrolls 3 pages at once

[leissa]

Thanks for the great tool.

I noticed one annoyance: Mouse wheel scrolls 3 pages at once instead of one page at a time.

I'm not quite certain what to do about this - tdf scrolls once per mouse 'event', as defined by crossterm's EventStream struct. If you try this on a touchpad, or something that's more granular with how it sends scroll input, you'll see this. However, I do understand that your mouse may just increase its sensitivity by sending more events per scroll, and it's not really reasonable for tdf to automatically know how many scroll events corresponds to a single 'scroll' of the mouse.

I feel like the best solution for this would be some sort of scroll-factor or scroll-sensitivity option? Specifically, the scroll-factor option, which you can enter as an integer, could which defines how many scroll events to wait for before scrolling a single time? Or maybe, on the other side, the scroll-sensitivity option could be passed in as a float between 0.0 -> 1.0 and define what percentage of a scroll each scroll event should represent (e.g. 0.2 would mean you only scroll once per 5 scroll events)?

Do either of these options sound appealing to you or were you thinking something different?

Okay, so you are saying that one mouse wheel corresponds to several MouseEvents in crossterm? Can't you just empty the event queue after each scroll event?

@leissa PR #34 is an attempt at emptying the event queue after each scroll event. Would you be able to pull the code from the PR, build it, and let me know if it fixes your issue?

I've just tried #34. Unfortunately, the problem still persists. :(
