I think I'm starting to like fantasai's proposal.

(Maybe 'mixed' should be called 'normal' or 'auto', but I'm not sure.)

I'm not completely clear what the proposal for 'sideways' is. Fantasai's 
proposal cryptically said "sideways (or sideways-rl)". In particular, what 
does setting

    writing-mode: vertical-lr; text-orientation: sideways

do?

And if that turns characters clockwise, is the value actually still needed? 
between 'text-orientation: mixed' and 'writing-mode: sideways-rl' you cover 
most cases of text turned clockwise. What's missing then is _inline_ CJK 
turned sideways. Is that needed?


'text-orientation: use-glyph-orientation' isn't mentioned in fantasai's 
proposal, but I assume it is still there (and still at-risk)?
