Specifies an easing applied to the waveform value. The default is
Linear, meaning the waveform range of 0...1 is used directly (mapped to the
High range). An
Easing provides a different mapping for the values.
Note this value is applied on top of the
Waveform, thus typically
Sawtooth are used if an
Easing is desired.
