description: Threshold the selected channels, so that values less than the given Threshold Value become zero, and values greater than or equal become one.
If the Threshold Softness is nonzero, values less than value-softness become zero, values greater than value+softness become one, and values are linearly interpolated inbetween.
Note that when thresholding color values with a non-opaque alpha, the color values should in general be unpremultiplied for thresholding.
