Re: [csswg-drafts] [css-color] black point compensation (#299)

ICC 4.2 defines rendering intents including blackpoint compensation. This is primarily useful for CMYK where, epecially on poorer quality papers, the deepest black is much lighter than Lab 0 0 0.

For RGB colorspaces, it is typical to convery assuming RGB 0 0 0 is Lab 0 0 0 and then do any flare compensation as a separate step.

For video, especially narrowband video with headroom and footroom, a PLUGE signal is used to set a true black.
