Channel Quantizer
Quantize in Hue, Saturation, Value, and/or Chroma
This shader reduces the number of steps, introducing posterization in several channels. For all channels except Value watch the Vectorscope / Chromaticity view to understand the behaviour.

Installation
Unzip and place files into the /vol/.support/shaders folder which is the same as
- Linux: /usr/fl/shaders
- MacOS: /Library/Application Support/FilmLight/shaders
