 `view.rotateToSelection` (desktop app, View › Rotate View to Selection) turns the view about the center of the canvas to
 the angle the selected objects share (`selectionRotation` in `document.inspect`, 0 when their angles differ), so their
 bounding box is square to the window. It returns `{angle}`, and with nothing selected it returns "nothing selected".
