[$] Wayland support (and more) for Emacs

Jeffrey Walsh started off his 2021linux.conf.au presentation with a statement that, while 2020 was not the greatest year ever, there were stillsomegood things that happened; one of those was the Emacs 27.1 release.This major update brought a number of welcome new features, but alsoled to yet another discussion on the future ofEmacs. With that starting point, Walsh launched into a fast-movinglook at the history of Emacs, why users still care about it, what changesare coming, and (especially) what was involved in moving Emacs away fromthe X window system and making it work with the Wayland compositor.
