Re: [fxtf-drafts] [css-compositing-2] Remove or fix definition of plus-darker (#447)

The CSS Working Group just discussed `[css-compositing-2] Remove or fix definition of plus-darker`, and agreed to the following:

* `RESOLVED: define plus-darker based on research results in the issue and raise issue to deal with max/min in various cases`

<details><summary>The full IRC log of that discussion</summary>
&lt;bramus> astearns: there was a q here on what was actually implemented, and we got some feedback from impl. is that enough to know what to do?<br>
&lt;bramus> vmpstr: generally we want to align with webkit here in the spec<br>
&lt;bramus> vmpstr: and then implement from thereon<br>
&lt;bramus> dbaron: yes, it seems like the results I got from testing with safari and what apple  (simon) says agrees, so we should put that in the spec<br>
&lt;bramus> … one side comment is that i am interest in feedback from color experts on how this is supposed to work outside of srgb<br>
&lt;chris> q+<br>
&lt;bramus> … some formulas have max fns in them in interesting ways that assume the color space runs from 0 to 1 (I think)<br>
&lt;bramus> … would be good to get that written down by experts<br>
&lt;astearns> ack chris<br>
&lt;bramus> … so this is a call for interested folks to look at it<br>
&lt;bramus> chris: I can give a brief explanation<br>
&lt;bramus> astearns: or we could resolve to define this for srgb and open issue for the rest (if that is needed)<br>
&lt;bramus> chris: sgtm<br>
&lt;bramus> … and that was a good question dbaron<br>
&lt;bramus> dbaron: (agrees)<br>
&lt;bramus> astearns: would the possible improvmenets need to be added to ???<br>
&lt;bramus> dbaron: not all, maybe 3 or 4<br>
&lt;bramus> astearns: PROPOSED RESOLUTION: define plus-darker based on research results in the issue and raise issue to deal with max/min in various cases<br>
&lt;bramus> RESOLVED: define plus-darker based on research results in the issue and raise issue to deal with max/min in various cases<br>
