```
Server.resize(_:by:toward:)(pane: Pane, by: Int, toward: ResizeDirection) -> ()
```

Nudges a pane's boundary, leaving the rest of the layout to absorb it.

The counterpart to setting a size outright: this is how you say "a
little more room" without first reading what the pane has and doing the
arithmetic. Which pane grows depends on the direction — see
``ResizeDirection``.

## Raises

- `TmuxError`
