Rigid hscrolling is well defined with proportional fonts.

but it seems to me it would interact badly with window width changes?

I did outline something that should (I think) deal with that aspect in particular in a post last month, but Eli did point out it would still necessitate further nontrivial changes to display code - he's got a lot on his plate already (understatement) -see:
Message-ID: <address@hidden>

My minor concern is that if the inverted hscrolling method is implemented and an emacs is formally released with it, then a subsequent implementation of rigid (including window-width-aware rigid) hscrolling might also have to deal with offering the inverted hscrolling behaviour some users have by then become accustomed to as an option. That would likely be more horribly complicated than only supporting the one type of hscrolling. It's premature to worry about, though, there'll presumably be a period with bidi code public in branch and then trunk, but not an emacs release.
