There was a problem hiding this comment.
Assuming the tests validate that the matrix values are correct, looks good to me.

This builds on #139, which added absolute color conversions (conversions without chromatic adaptation). The default method implementations added there use the chromatically-adapting methods and undo adaptation through additional matrix multiplies. For efficiency, we can do the absolute conversions using matrices that do not include adaptation in the first place.
This PR does that for ProPhoto RGB. More to follow.
