Re: [csswg-drafts] [css-color-hdr] Allow H1 to be zero, or not? (#11786)

So this entire issue was caused by mixing up perceptually-linear stop-based headroom (log units, as used in the rest of the CSS Color HDR spec and the ISO specs as well) with light-linear headroom used in the original proposal.

Using stop-based throughout removes the inconsistency and also simplifies the calculations (no need to log the headroom values first)

@ccameron-chromium the WPT would need to be updated for this.
