Add option to choose direction

[renestalder]

Want to choose the direction of the Knob. At this time it goes from right to left, like a clock. But it would be useful to have an option to set the direction to go from left to right.

Do you have a quick fix for that? Tried to mirror it horizontal with CSS scale, but then of course, the whole touch/mouse controls are wrong.

I also found the need to choose the mouse wheel direction: is it possible to invert its behaviour?
Using a knob to control volume works in the opposite way as supposed (scroll down = increase volume).
