If I understand correctly (and I may not), the proposed function just takes properties into account (like `invisible' and `display'), but does not compute pixel sizes at all? I can see how that may be useful in some cases (and is very different from `window-text-pixel-size'), so I think adding something like that would be nice. But the name is confusing -- it sounds like it's computing the displayed width, and it's not -- if there's images or text with a different font in there, it's not taken into account? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
