 /**
  * A simple item containing a title and subtitle label.
  *
  * This is mainly intended as a replacement for a list delegate content item,
  * but can be used as a replacement for other content items as well.
  *
  * When using it as a contentItem, make sure to bind the appropriate properties
  * to those of the Control. Prefer binding to the Control's properties over
  * setting the properties directly, as the Control's properties may affect other
  * things like setting accessible names.
  *
  * Example usage as contentItem of an ItemDelegate:
  *
  * ```qml
  * ItemDelegate {
  *     id: delegate
  *
  *     text: "Example"
  *
  *     contentItem: Kirigami.TitleSubtitle {
  *         title: delegate.text
  *         subtitle: "This is an example."
  *         font: delegate.font
  *         selected: delegate.highlighted || delegate.down
  *     }
  * }
  * ```
