Yes, if you want to synchronize the scrolling between two windows, you
can indeed do that (not that it's a separate issue from synchronizing
the cursor).  You can use `set-window-vscroll` for that.
It can be fiddly as well, tho.

Instead of inserting virtual newlines in only one window, you could take the
opposite approach and really inserting the newlines in the buffer and
then hiding those newlines in all other windows.

Of course, that would still require taking care to remove those newlines
before the buffer is saved (and things get even more delicate if you
want to allow editing the buffer).

That might be a much easier option.
