Hmm. I would then assume that Emacs has rudimentary rendering support in Cocoa, but is otherwise treating it as a variant of X11, and not the fully different graphical system it presumably is. Emacs still has no full-fledged Cocoa integration. That is still only available in the Aquamacs fork, as far as I know: http://aquamacs.org/

You've never used Emacs with Cocoa or looked at any source code integrating Emacs with Cocoa; have you?

This is true. I hope I did not give a contrary impression? I was, somewhat briefly, aware of some of the complexities of Emacs running under NeXTSTEP (not the text-only Emacs 18 included with NeXTSTEP, but proper Emacs 19 with NeXTSTEP windowing support), but that was (obviously) many years ago, and I don’t claim to remember any of it. And I was certainly not involved in implementing any of it.
