Re: [csswg-drafts] [css-inline][css-writing-modes] definition of the central baseline

Exactly. Fonts can have horizontal and vertical metrics. In vertical 
metrics, baseline is vertical, at the middle of the glyph, and the 
right half is still called ascent.

See the chart in [this page at 
Microsoft](https://www.microsoft.com/typography/otspec/gpos.htm). Or 
the chart in 
[kanji-database](http://kanji-database.sourceforge.net/fonts/opentype.html)
 (find a big chat of "漢") has "ascender" and "descender", though, it's
 Kanji character so maybe a little hard to understand how to apply it 
to Latin characters. At the bottom of [6.3. Line-relative 
Directions](https://drafts.csswg.org/css-writing-modes-3/#line-directions)
 has a picture of baseline in vertical metrics when I got the same 
question before.
