Detailed Description

Asymptotic or 'Squeeze' scaling, with a linear (main) part.

This scaler scales between -1 and 1. Between center()-width() and center()+width() this will happen linearly. The value at width() will be linedge(). Therefore, linedge should be set to a value near 1, like the default 0.95. Outside the width() boundaries, a 1 / (1 + x^2) function will make sure the output will be between -1 and 1. Thus, this scaler acts as a reversible squeeze function, with a non-deforming (linear), fast central part.
