In the WebVTT video subtitle format, subtitles can be horizontal, vertical growing left, or vertical growing right. The natural text direction of NSTextView is horizontal; with setLayoutOrientation(_:) I get vertical text growing left. How can I get vertical text growing right? The documentation says that with setLayoutOrientation(_:) the text view's bounds are rotated by 90° clockwise, but manually rotating them by -90° with boundsRotation = -90 just rotates everything, including the text which should have the same orientation as before, just expanding in the opposite direction.
