First, thank you for taking the time to look into this, and for writing up a sketch of a proposed fix. I don't have time right now to properly consider the issues you raise, but I do intend to maintain `scroll-in-place', and so I will keep your comments in my list of things to look into. Second, ``wrong'' is a pretty strong word. You are correct that the current design is based on certain assumptions --- most notably, the assumption that display lines have constant height --- and the general validity of those assumptions may change over time. But I think that when `scroll-in-place.el' was last modified, in 1994, the assumptions that underlie the design were largely valid. (Last modified by me, in any case. I see that people have made some minor hacks to the version that is now distributed with XEmacs, but they appear to be insignificant.) To a great extent, I think that the constant-height line assumption is still often true, although I agree with you that it is increasingly less often true, and that `scroll-in-place' should be updated to deal with variable-height lines in a more graceful manner. I will give this matter some thought, and think about the approach that you propose. Exactly when, though, I can't say.
