Description

On mac trackpads right clicking with two fingers triggers a scroll event with value 0. The old code would force the value to -1 and cause the slider to scroll down. The same would happen when the two fingers would be lifted. It would be especially annoying in the layers slider when trying to add a pause because the slider would move to a different layer before the context menu would appear.

Tests

I built the application and tested if behaviour is still wrong. The bug is not present any more and scrolling is smooth.
