Both "eaVert" and "mongolianVert" are not pure geometrical, but consider
east asian scripts, so that such characters are excluded from the rotation.

Yes. That makes it possible to render "vert" and "vert270" by
incorporating the "TextPreRotateAngle" into aTextBoxMatrix in

I found that I was confused with the name "loext:text-direction", and connected it to writing-mode.
In different context direction may mean writing direction in Bidi text, as in [1].
Is that new
"loext:text-direction" attribute only intended to rotate text for RL_TB writing mode?
( wordArtVert and wordArtVertRtl should also be excluded in that case? )
