This adds a new output color effect: grayscale. It takes RGB color as input and computes a gray pixel color using the luminance formula for linear sRGB: Y = 0.2126 * R + 0.7152 * G + 0.0722 * B Just like the other color effects we have, this only works for sRGB and are not enabled when color-management is on. Note: although the technique is designed to be applied in linear, it's costly to convert to linear and then back to electrical. As doing the conversion in electrical still gives a reasonable result, we do it this way. When we add support for color effects with color-management on, we'll apply the effect in linear.
