Wayland support (and more) for Emacs

I had spoken with one of the Emacs/Guile developers at LibrePlanet in '17 or '18 (I think). Performance was definitely an issue, but a lot of that problem was rooted in the fact that Emacs and Guile represented text chunks in very different ways and the need to convert back and forth between the two. I do not remember the details, but there was some discussion of the issue in the repo along side of the code. Unlike the GUI, Lisp is fundemental to the Emacs engine itself and the extra boxing/unboxing on every Lisp call is neither trivial nor efficient regardless how much faster the Lisp engine itself is. From what I recall of the conversation, this was seen as a significant problem and neither interest nor resources were available to address it.
