I have a couple of suggestions.
Sounds like the approach/sample-code/etc has all been pretty much
figured out and that you already kinda know what needs to be done and
how to go about it (in principle). Could I suggest putting that into
a one/two page document and attach it to Mr. Schroeder's "Resources-Bidi"
page ? At a minimum, if/when this subject rears its ugly head again you
can simply post a URL to answer all these rather common questions :)
After doing that (again, just some thoughts and compilations of whats
already been posted, nothing too detailed as that would be left for
Q&A's), I'd highly recommend posting to the various emacs lists (as
well as mailing-lists) soliciting help. I'm sure there are plenty of
people out there familiar with the display engine might be looking for
a challenge. The point is, having searched for Bidi+emacs info, no
where did I see a clear indication of its current status and what's
required for its completion, let alone a 'call for help' which is
where this effort stands.
With the various Bidi efforts out there and resident expertise, I don't
think this issue would fall through the cracks given enough publicity
about this topic and its needs. Certainly Handa-san, et al might want
to re-jump in, no ? :-)
