[feature request] skew factor for sliders

[d.healey]

A skew factor entry box in the property editor would be handy :)

[Christoph Hart]

@d-healey The middlePosition property does exactly that but more intuitively.

[d.healey]

@Christoph-Hart I feel so dumb sometimes :)

What about with a bi-polar slider where you want the skew to go from the middle position out?

[Christoph Hart]

@d-healey Yes, that's not possible at the moment. I know the JUCE class has a symmetric skew, but I'm afraid using this will break our current middlePoint implementation.

You can always roll your own with some highschool school math though...

@d-healey @Christoph-Hart Here's what I use:

    // Get SkewFactor from MidPosition
    inline function getSkewFactor(start, midPosition, end)
    {
        return Math.log10(0.5) / Math.log10((midPosition - start) / (end - start));
    }
    
    // Map from Skew
    inline function mapFromSkew(valueNormalized, skew, start, end)
    {
        return Math.pow(10, (Math.log10(valueNormalized) / (1/skew)) + Math.log10(end - start)) - start;
    }

Would adding a slider.setSkew function allow us to avoid breaking the middlePoint setting?

The problem with this is the display value of the slider won't match the output value.

Its been a long outstanding request that we can add a custom value list to the slider for this...like in KnobMan (1,2,3,4,5,6,7 etc.)
