Re: [csswg-drafts] [css-fonts] Vertical text doesn't play nicely with font-style and font-stretch (#4044)

> > This was discussed at the most recent OpenType F2F, and there was interest in the font using two distinct low-level physical controls for vertical stretching and horizontal stretching, and the browser/app determining which of those types of stretching to use.

Note that for Roman fonts, using the 'wdth' axis all the time should be ok -- it is only when characters are upright that the 'vwid' axis would give a better result, when matching other squashed in that dimension, for example, fonts. I am of course speaking out of turn with little knowledge of CJK font matching using that axis...
