I didn't think in it before, I don't know where TLB would be used. Now,
I can think it is used in Indic scripts (in which the glyphs usually
hang from the base line), then TRT for Arabic would be the logical
choice, imagine Devanagari mixed with Arabic. TRB wouldn't make any
sense for Arabic since it will break the way glyphs are connected
together, unless the glyphs are rotated 180 degrees which would be very
funny but almost useless.
