there is something mentioned in followingup-directions.tex

i removed top to bottom directions from luametatex because it made no
sense; one cannot do vertical typesettign without also looking at the
layout and other things

instead of directions we do rotation at the glyph level and such which
has less interference and more flexible

but ... i haven't looked at it recently (could be broken by other
features) as there is little demand for it
