Related notes:

This is effectively a proposal to support tatechūyoko (縦中横), 'length in side', typically translated as 'horizontal in vertical' [1]. This may be mapped into the CSS3 Writing Module's text-combine-horizontal property [2].

Note that this is not at all the same as using the writing-mode property to establish block and inline progression directions.

[glenn]: glenn thinks this isn't related to issue-159, so sean needs to elaborate if he thinks otherwise
