Detailed Description

A transfer function.

Each transfer function has an associated threshold value and a color. At the threshold value itself, the returned color will be the specified color. In other places, it will be a "lighter" color.

This function also depends on the neighbouring transfer functions; setUpperThr and setLowerThr must be called. For functions at the edge, use 0/4095 as lower/upper thresholds.
