I don't think the inputs here are sufficient (e.g. for keywords), maybe just
take a StyleValue?

Also probably a good idea to put any functions that we expect will grow to be
big into a cpp file.

Keyword is also a StyleValueType.

Moved functions into the cpp file.

But we need to verify that we're passing in a sane keyword for a given property,
right? Similarly, some properties will accept lengths but not percentages (both
of which are represented by a LengthValue).

Ah, I see. Done.
