Color:
* Accelerated sRGB <=> linear conversion using lookup table, this can speed up
loading of images in the compositor and simple renders quite a bit.
* Dithering now uses the Floyd-Steinberg algorithm. Previously it would simply
randomize each pixel slightly, adding noise, now that should be reduced.
Patch #29309 by David M.
