does anybody actually use that in practice?  i'm not a fan of adding
purely hypothetical i18n features for no practical benefit.

OOXML doesn't have "leftVertical", and the CSS draft linked by Regina
also has only one "side" mode.

CSS calls it "inter-character", maybe we should use the same name.

also, good to specify the writing direction of the ruby annotation
itself, which seems to differ from the one of the base text in this case.
