Mousewheel On Sliders And Mixer

Some components in the UI have support for mousewheel, but not all.
Missing are most notably all horizontal sliders plus the gain-sliders in the mixer view.
It would be a great improvement to add this.

I’m on Linux, version 2.1.

Sounds good. I’m at school now so i can’t test how they actually work.
It would be great if you could move sideways in the mixer with mousewheel.
Also mixer sliders with mousewheel is nice option.
