The Working Group just discussed `Angle for oblique->normal threshold should be lower end of common obliques not 20`, and agreed to the following:

* `RESOLVED: Start searching for obique starting from 11deg`

<details><summary>The full IRC log of that discussion</summary>
&lt;fantasai> Topic: Angle for oblique->normal threshold should be lower end of common obliques not 20<br>
&lt;fantasai> https://github.com/w3c/csswg-drafts/issues/2539<br>
&lt;fantasai> github: https://github.com/w3c/csswg-drafts/issues/2539<br>
&lt;frremy> fantasai: in the font matching algorithm, we start searching from 20deg then go up from there<br>
&lt;frremy> fantasai: 20deg is an average<br>
&lt;frremy> fantasai: we should probably search from the minimum value<br>
&lt;frremy> chris_: if the mimimum is 14 we should start searching at 7<br>
&lt;fantasai> "If no match is found, oblique values greater than or equal to 20deg are checked in ascending order followed by oblique values below 20deg in descending order, until 0 is hit."<br>
&lt;frremy> fantasai: the spec says:<br>
&lt;frremy> fantasai: (see above comment)<br>
&lt;frremy> florian: 14 not 7?<br>
&lt;frremy> myles: if you have 13deg and 80deg you want 13deg<br>
&lt;frremy> fantasai: so we set 7deg<br>
&lt;frremy> myles: but what about 6deg and 80deg?<br>
&lt;frremy> florian: binary search, we look in both directions?<br>
&lt;frremy> myles: I don't want to change the algorithm<br>
&lt;frremy> myles: I think we should set the value as 11deg<br>
&lt;frremy> myles: because this seems better than 8deg<br>
&lt;frremy> fantasai: 11 is a lower-bound italic<br>
&lt;frremy> fantasai: 8 would be pushing it<br>
&lt;fantasai> s/italic/of typical italics/<br>
&lt;frremy> astearns: alright, any objection to start searching at 11 and see how it goes?<br>
&lt;frremy> myles: (disgression on the negative angle)<br>
&lt;chris_> It goes to 11!<br>
&lt;frremy> RESOLVED: Start searching for obique starting from 11deg<br>
&lt;florian> It goes to 11!  -> it starts from 11!<br>
