* 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
