docs: Move to the new content scene. Move the current content scene, if any running, to invisible
  state (see {@link ContentScene#hide()}); push the new content scene to the stack if it is not
  yet; or run {@link #goBackTo} to roll stack back until the specified content scene is reached,
  then move new content scene to visible state (see {@link ContentScene#show()})
