Re: [csswg-drafts] [css-transforms] After #6320 there's no way to get an identity transform for interpolation of perspective (#6488)

The CSS Working Group just discussed `identity transforms`, and agreed to the following:

* `RESOLVED: Add perspective(none)`

<details><summary>The full IRC log of that discussion</summary>
&lt;fantasai> Topic: identity transforms<br>
&lt;fantasai> github: https://github.com/w3c/csswg-drafts/issues/6488<br>
&lt;fantasai> emilio: I wasn't on last week's call<br>
&lt;fantasai> emilio: seems fine to add a new value to represent this<br>
&lt;fantasai> emilio: ...<br>
&lt;smfr> q+<br>
&lt;Rossen_> ack smfr<br>
&lt;fantasai> smfr: I'm ok with something like perspective(infinity)<br>
&lt;astearns> we ran out of time last week to get to a resolution<br>
&lt;fantasai> smfr: I do wonder about the lack of units, wonder if it adds complexity to animations and blending<br>
&lt;fantasai> TabAtkins: perspective is normalized to matrix, so shouldn't be a problem<br>
&lt;fantasai> TabAtkins: addition with infinity would swamp whatever value the other side was, so don't have to worry in that case either<br>
&lt;fantasai> Rossen_: sounds like we're going forward with infinity?<br>
&lt;fantasai> astearns: there was also the suggestion of perspective(none)<br>
&lt;fantasai> TabAtkins: smfr brought up that animation-iteration-count uses 'infinite' whereas calc() uses 'infinity', so 'none' would dodge the issue<br>
&lt;jfkthame> +1 to perspective(none)<br>
&lt;fantasai> Rossen_: is everyone ok with none?<br>
&lt;fantasai> RESOLVED: Add perspective(none)<br>
