It basically doesn't work at all with display-time word-wrapping turned
on.
I presume much of the problem is with emacs primitives (vertical-motion
etc) though.
With word-wrapping turned off, it kinda-sorta works.
I noticed the following:
(1) It seems extremely slow -- moving from line to line is noticeably
laggy, and sometimes will just ... hang for a while, even if
there's no wrapped lines at all.
(2) It seems to cons a lot; even just a bit of movement results in
frequent pauses to garbage collect (again, this happens even
without any wrapped lines).
(3) When the default face is variable-pitch, the positioning with
C-n/C-p seems a bit "rough". V.W. fonts, one can't be completely
precise, but it probably ought to at least use some notion of
pixel goal column to avoid the tendency of the horizontal position
to drift with a lot of vertical movement.
I expect emacs primitives will need improvement to work for the
word-wrapping case (and display-time line-prefixes which I've hacked up
locally), so perhaps they can be improved to work better in general too.
