Each lookup table is an array of 256 pixels, 768 bytes. I build them with the
gimp. See below.

Nope the same result is not achievable with videobalance. It's not a
hue/contrast/brightness change, each color is mapped to a new one with no
simple relation with the previous.
If you give me a couple of hours (maximum tomorrow morning) I'll post a simple
patch with a single plugin + several presets so that it's clear what we're
talking about, then we'll see if a baseclass it's really worth.
