The Emacs terminal (M-x term) seems to be a reasonable approximation, with the scroll-left and scroll-right commands changing the margins' separations. This is an example of a terminal that has lines with left-to-right character paths and lines with right-to-left character paths. (Such lines are necessarily separated by blank lines.) Geometrically, column positions on left-to-right and right-to-left character paths are incomparable - resizing the window and scrolling move them differently. Richard.
