Of course we can't reuse the existing glyph matrics, but,
was it the conclusion that we can't use `struct it' without
a glyph matrics?
For instance, it seems to me that doing this is possible.
(1) call init_iterator with ROW == NULL
(2) call reseat with POS == (line-beginning-position)
(3) call move_it_to with TO_CHARPOS == (point)
(4) it->hpos is the current column.
