Add epsilon for color rounding.

Colors that have a channel value of exactly 0.5 were getting incorrectly
serialized as having an integer value of 127 (as opposed to 128) due
to float arithmetic problems.

This change also gets Red(), Green() and Blue() out of CSS
serializations, and instead uses the underlying float values which
should make things more robust.

Eventually my goal is to remove Red(), Green() and Blue() entirely.
