```
Server.rotate(_:upward:)(window: Window, upward: Bool) -> ()
```

Shifts every pane in a window one position around the layout.

The layout itself is untouched: the panes move through its positions,
each taking the size and place of its neighbour. Ids do not change, so
panes you already hold stay valid — but their indices do, which is what
makes this different from ``swap(_:with:)-(Pane,Pane)``.

- Parameters:
  - window: the window whose panes move.
  - upward: each pane takes the next numerically lower position, which
    is tmux's own default. `false` sends them the other way.

## Raises

- `TmuxError`
