Emilio Cobos Álvarez 1ee4fdcb2a Bug 1782595 - Distinguish between "preferred" and "used" color-scheme. r=tnikkel
The "preferred" one is the behavior we have for chrome docs, where we
fall back always to the document's preferred color-scheme rather than
falling back to light.

We'll use this in the next patch.
