[Feature Request] Visual indicator for scrolling?

[muzikbike]

Is your feature request related to a problem? Please describe.
ScreenToGif produces a visual effect to indicate when mouse buttons have been pressed, however there is no such visual indication for when the scroll wheel is moved. Displaying something in this situation may be useful.

Describe the solution you'd like
There should be some sort of visual feedback for scroll wheel usage in ScreenToGif, perhaps as a colored triangle pointing in the scroll direction, or through other colors of circles.

Describe alternatives you've considered
Not having it at all, which would be sad.

Additional context
Discussed earlier in #1292.

There should be one indication for scrolling up and another for scrolling down. Also relevant would be the case of scrolling left and right, for the few existing mice that have a supplementary horizontal scroll wheel; A4Tech had a small selection of these in the late 1990s to early 2000s, and no I don't know how they managed to fit that information into the PS/2 protocol. More recent implementations of horizontal scrolling include the Logitech MX Master line of productivity mice.

Turns out that I can indeed bind horizontal scrolling to buttons using G-HUB and use this to test the functionality accordingly.
