Re: [csswg-drafts] [css-transforms] Smarter interpolation of truncated transform lists

The Working Group just discussed `[css-transforms] Smarter interpolation of truncated transform lists`, and agreed to the following:

* `RESOLVED: pad the shorter one with identity functions, find the common prefix, interpolate common prefix pairwise, interpolate the rest matrix-wise.`

<details><summary>The full IRC log of that discussion</summary>
&lt;Rossen> Topic: [css-transforms] Smarter interpolation of truncated transform lists<br>
&lt;Rossen> github: https://github.com/w3c/csswg-drafts/issues/927<br>
&lt;ericwilligers_> Brian: (summarizing) There was a proposal for when we have mismatched transform lists to do something smarter than matrix interpolation<br>
&lt;ericwilligers_> Brian: We resolved on some behavior (April 2017) but when implementing, spec text did not match what was discussed in WG.<br>
&lt;ericwilligers_> Brian: We implemented what is in spec text but we want to do something smarter: interpolate common denominator and use matrix interpolation for the remainder<br>
&lt;ericwilligers_> s/denominator/prefix/<br>
&lt;ericwilligers_> dirk: do other implementers also want to change?<br>
&lt;ericwilligers_> dino: we should do this: go as far as you can, smoosh the rest<br>
&lt;ericwilligers_> ian: will have to check with Waterloo team<br>
&lt;ericwilligers_> rossen: no objection<br>
&lt;ericwilligers_> pad the shorter one with identity functions, find the common prefix.<br>
&lt;ericwilligers_> interpolate common prefix pairwise, interpolate the rest matrix-wise<br>
&lt;ericwilligers_> dirk: proposal from fantasai to do the same from the right if they have a common suffix.<br>
&lt;ericwilligers_> tab: don't like it - common to have ambiguous situations<br>
&lt;ericwilligers_> dirk: agree<br>
&lt;ericwilligers_> tab: prefer prefix over suffix, prefer not to try to do both<br>
&lt;birtles> I agree<br>
&lt;ericwilligers_> RESOLVED: pad the shorter one with identity functions, find the common prefix, interpolate common prefix pairwise, interpolate the rest matrix-wise.<br>
