Server.rotate(_:upward:)

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.
