I've checked in changes that make text decoration depend on vertical
vs horizontal *typographic* mode rather than *writing* mode.

Note that this makes text-emphasis-position and text-underline-position
use the [over|under] value pairing instead of the [left|right] for the
sideways-lr/rl values of 'writing-mode'. (The logic for this is that all
text, including CJK, is rotated in these modes--CJK text would tend to
use vertical-lr/rl, which allows for upright characters and allows for
sideways characters via 'text-orientation'.)


Please let me know if there are any concerns with this approach.
