I'm late with my homework for tomorrow's meeting,
so I'm giving you a quick summary of what I have
come up with so far.
The hue/saturation effect has bad quantisation artifacts
when the colour model is YUV and the sliders are set to
anything but unity. I have attached a test project to
demonstrate the banding noise; it's glaringly obvious
when you view it at 200% size.
There is another concern bugging me: LCD displays with
lacking colour depth. I get banding artifacts no matter
what on my LCD monitor when I display synthetic gradients
that are free from noise and dithering. (like in my testcase)
I'll compare with my CRT monitor, and see what difference
it makes.
