/**
* Levels version 1.2
* by Christian Cann Schuldt Jensen ~ CeeJay.dk
*
* Allows you to set a new black and a white level.
* This increases contrast, but clips any colors outside the new range to either black or white
* and so some details in the shadows or highlights can be lost.
*
* The shader is very useful for expanding the 16-235 TV range to 0-255 PC range.
* You might need it if you're playing a game meant to display on a TV with an emulator that does not do this.
* But it's also a quick and easy way to uniformly increase the contrast of an image.
*
* -- Version 1.0 --
* First release
* -- Version 1.1 --
* Optimized to only use 1 instruction (down from 2 - a 100% performance increase :) )
* -- Version 1.2 --
* Added the ability to highlight clipping regions of the image with #define HighlightClipping 1
