Re: [csswg-drafts] [css-rhythm-1] Why is 'none' an alias to '0'?

There's no reason to floor the value. Rounding to the nearest 0-sized step *effectively* disables rounding, but mathematically it's continuous and consistent with just rounding to the nearest n-sized step. We added `none` because there was discussion of having line-height step take effect might have some behavior side-effects aside from simply rounding. E.g. it might affect `line-height: normal` calculation differently. (IIRC that was the context of adding `none`.)
