Allows global increase and decrease of a channel:
That middle point goes up and down the dashed line, meaning that every value in the channel is higher or lower than it otherwise would be, except 0 and 1.
0 and 1 stay fixed where they are.
Also allows increase of red, green or blue independently of brightness with the option of excluding selected hue ranges.

I figured out that the best use of this shader is for tint removal after using the White Point shader, as there have been many occasions where there has been a red tint even with an an optimal white point.
I also suggest using Distance_to_grey.fx after this one to act as a debugging/calibration tool.

Update: Linearises the RGB before adjustment and re-gamma corrects it afterwards.

UPDATE: Included "avoid_grey" option which makes the shader have less of an effect as the chroma decreases. Makes the result look better when using rgbDeltaAmnt and greyDeltaAmnt. I have aslo removed split because Before and After work fine.

Now just an RGB adjustment shader, but allows application on certain hue ranges (as in my Colour Isolate shader).

Added version that adjusts the colour in the xy space, but keeps the same Y (brightness).
