 * Copy-mode's visible screen (the "screen" field) is filled from one of
 * two sources: the original contents of the pane (used when we
 * actually enter via the "copy-mode" command, to copy the contents of
 * the current pane), or else a series of lines containing the output
 * from an output-writing tmux command (such as any of the "show-*" or
 * "list-*" commands).
 *
 * In either case, the full content of the copy-mode grid is pointed at
 * by the "backing" field, and is copied into "screen" as needed (that
 * is, when scrolling occurs). When copy-mode is backed by a pane,
 * backing points directly at that pane's screen structure (&wp->base);
 * when backed by a list of output-lines from a command, it points at
 * a newly-allocated screen structure (which is deallocated when the
 * mode ends).
