[css-writing-modes-3] vertical-lr and vertical-rl

[francescorn]

It would be nice to have all languages, such as English, to have a default of text-orientation: upright in vertical-lr and vertical-rl.

(Also vertical-lr and vertical-rl currently behave the same as sideways-lr and sideways-rl respectively in languages such as English.)

I realize this is a bad idea.
