I’ve attached a half‐assed attempt at a lisp‐powered fullscreen for
macOS. It won’t work elsewhere.

At the moment it makes the frame too wide by 35 pixels. I seem to
recall reading about that at some point, but I can’t remember if
there’s a way to do it properly. It also seems to make the frame a
little too tall.

Maximising instead of resizing would work, but once the decorations
are disabled maximise stops working, and maximising then removing
decorations leaves a gap at the top of the screen.

I guess I’ll have to look into whether maximise can work with
undecorated frames. Presumably it’s caused by the removal of the
resize bit from the styleMask.
