Depends on how you scroll, I guess.  Applications where "point" stays
put when it goes out of the viewport need to be scrolled by moving
"point".

But if you have in mind the automatic movement of point when the
window is scrolled, then yes, it's quite unique to Emacs, but it isn't
about scrolling, it's about the fact that any movement of point
modifies the region.
