Recreate the group xfade curve in scriptnode

[tomekslesicki]

I'm sure somebody knows what's the magic default xfade curve at gamma factor 1? I'd love to recreate it in scriptnode, but I'm having a bit of trouble getting the skew factor and the curve right.

The default curve is linear

@Christoph-Hart could you tell me more about the skew factor applied to the gain of the group xfades?
