/**
 *
 * This post-process allows the modification of rendered colors by using
 * a 'look-up table' (LUT). This effect is also called Color Grading.
 *
 * The object needs to be provided an url to a texture containing the color
 * look-up table: the texture must be 256 pixels wide and 16 pixels high.
 * Use an image editing software to tweak the LUT to match your needs.
 *
 * For an example of a color LUT, see here:
 * @see http://udn.epicgames.com/Three/rsrc/Three/ColorGrading/RGBTable16x1.png
