"Book-like" text rendering

[Dmitry Antipov]

With modern wide (16:9 or 16:10) screens, there is the following question:
is it reasonable/usable to have a feature to render the text in two horizontally
adjacent windows like it's "rendered" in the book?

I.e. with the following window layout (both A and B has, say, 50 lines):

+-----------+-----------+
| A         | B         |
|           |           |
|           |           |
|           |           |
|           |           |
|           |           |
+-----------+-----------+

1000-lines text is initially 1..50 lines in A and 51..100 lines in B, with
current window A. When the cursor is at line 50 of A and moved to next line,
it goes to window B, line 1 (of window B and so line 51 of the text); when
the cursor is at line 50 of window B and moved to next line, it goes back to
line 1 of window A, and text is scrolled in both windows so A shows lines
101..150 and B shows lines 151..200, etc.
