I have no idea how it would work but perhaps someone at some point pass around here and give an idea or I get some lightning strike in the shower.
Anyway, I don't think I will be able to come up with a token-wise approach for this, but what I could have is some alternative filter that sets the tokens width and height assuming they are top to bottom and have a draw tokens function that understands drawing vertical text.
Probably need to figure some word-wrapping for vertical text too.
Additionally I also need to add height since it will need some height limit for word-wrapping.
