Blargh.

It looks like "legal" range RGB uses 64-940 (as you said) while "extended" range uses 4-1019.

Why is this even a thing? Who said, "Oh, you know, we have a completely defined signal space with definite boundaries, but we're going to artificially not use all of it."

EDIT: I wonder if I'm ever truly going to finish this thing, or if I'm going to take another left hook.

EDIT: I'm tempted to just have this thing document that you need to expand any limited RGB range before using it.

EDIT: I think I got it. I'll follow up with unit tests tomorrow.
