Currently it is possible to define an interval, however this is a minimum interval, which ignores events until that value is reached.
However if I choose a very small interval like 0.001, it is possible that each event will advance 0.003, so in the end that is the real interval.
So what I want is that, each mouse movement event fits the interval. But only when it is lower.
The idea is that it is done automatically, I would not want to have to adjust the sensitivity of each slider manually, and I suppose that with skewfactor it would be impossible.
