Try making a mode that allows point to be off-screen while scrolling
like it can be in most other editors.

It is a common misconception that Emacs cannot do this.  It can.  How
do you think it pulls the trick of allowing you to scroll pixel-wise
through a very large image?

Thanks. I never use Emacs to view images, so I didn't know we could do that.

It is a UI design decision in Emacs to always show point on screen.
But nothing prevents us from writing a mode that leaves point off
screen, or even abandoning that decision if we want (and I'm not
saying we do).  The infrastructure is there, check out the vscroll
thingy and window-vscroll.

Interesting. I may have to play with this functionality more after the feature freeze. Is (set-window-vscroll nil 500 t) supposed to move the window viewport? I didn't see anything change when I tried it in a quick test.
