Quick updatesFull spec plans

   -

   MathML full: split MathML3, chapter 3 would follow core closely,
   separate parts for non-normative parts


TAG Review process w3ctag/design-reviews#438
<https://github.com/w3ctag/design-reviews/issues/438>

BK: It is on the agenda. We have reviewers assigned: Dan Applequist, Hadley
Beeman and Alice Boxhall

BK: talked with some TAG/former TAG at blinkon/dev summit - generally
positive feedback.

No real other updates here.  There was an attempt to get some initial
review, but they didn't get to it and said that it would be on the f2f
(which was expected)

Operator spacing in scripts

 (38)

        review more examples

https://github.com/mathml-refresh/mathml/issues/38#issuecomment-557910479

NS: Fred added more examples. DC, you know TeX inside and out. Can you
verify this is using OpenType fonts?

DC: Yes, it is.

[everyone looks at the examples]

NS: I don’t like the TeX examples. I like the Gecko best, but the other
ones using MathML layout are better than TeX to me

DC: I’m not enamored with TeX. A little spacing might be good.

FW: Blink/Webkit use MathML spacing and Gecko uses half the space

DC: in TeX, the cmr7 fonts which are used by TeX for scripts are
deliberately made to be wide and have corresponding extra space around
them. Not true for OpenType fonts.

DC: If I had to pick, I’d go with Gecko. But if that’s harder, I’d go with
full spacing scaled down.

FW: For the implementation, MathML 3 spacing is easiest, but Gecko’s rule
is just an extra line, so not a big problem.

FW: Another option would be to add just one pixel

DC: That doesn’t scale, so I don’t like that.

NS: Does it make any sense to add an option to use TeX spacing rules?

FW: It would mean another CSS property. MathJax has the option to use
either rule.

NS: That would add complication when not in the scripts.

DC: I’d skip that for the first cut.

NS: I agree.

FW: For now, I agree let’s skip it.

BM: You need to document it, and that yet more work.

DC: It would be better to have some default that works most of the time.

Resolution: Use Gecko rule of half MathML spacing for scriptlevel > 0. Use
the script level at the core of the <mo>.

NS: we need to have a test as to where the script level is coming from.
(also check lspace/rspace)
Operator Dictionary update

        any updates on fixing up entries?

        Make things more consistent and general review & fixup #87 #6 #151
(David)

DC: Didn’t get chance to get to this

NS: It’s a rat’s nest, so it will take time.

NS: Next meeting in two weeks -- hopefully that gives some time to look
over it.
