But I don't know whether this is well-defined without pre-supposing some arbitrary text with to begin with (and what do you do with proportional fonts? Ligatures?). Rigid hscrolling is well defined with proportional fonts. I don't think Emacs tries to do hscroll properly with proportional fonts even now with all text L2R. It would be good to implement this. Handling R2L text too in a rigid way would not be much harder.
