You have to change the LUT in the draw process anyway, so each draw
process should make the same change to their respective LUT's. Once you
have the shared memory structures to direct this from the application,
actually applying this in multiple draw processes should be relatively
simple.

My comment on the abuse of Jon Johanson's rights;
After giving up raiding their neighboring countries the Norse men
have taken to raiding 15 year old kids in their bedrooms. Very sad.
