 Ffmpeg's current LUT functionality does not appear to be lookup table
 functionality at all, rather it seems to be formulaic modification to the
 individual pixels.  Adding industry standard LUT functionality would
 extend ffmpeg's utility.  Two such methods are:

 Pandora: [http://www.pandora-
 int.com/pandora/download/manual/lut3d_format.html]

 Hald CLUT: [http://www.quelsolaar.com/technology/clut.html]

 !ImageMagick has implemented Hald CLUT so a good example of source code
 could be found there (root code in enhance.c).
