  I'm not looking at the code now, but these were used for the idea of
logical sequence (like sequence of Unicode character that may contain
the composition characters), and visual glyph sequence that may be
composed from the logical sequence.  But trying to implement fully
elaborated glyph shaping layout in Squeak is now I think to be a
really obsoleted idea and cleaning them up would be a sensible thing
to do...
