[Therion] ceiling-meander

[Footleg]

That is news to me that the UIS have published these symbols with this error
in for years? I always took the published UIS symbols to be the definitive
reference, and inferred from them that the ticks indicated the direction
that the floor was lower (for floor height changes) and the tick indicated
the direction that the ceiling was lower (for roof height changes). So have
I drawn all my aven lines wrong for the past 5 years?
