/**
 * @brief An item that can be used as a title for the application.
 *
 * Scrolling the main page will make it taller or shorter (through the point of going away)
 * It's a behavior similar to the typical mobile web browser addressbar
 * the minimum, preferred and maximum heights of the item can be controlled with
 * * ``minimumHeight``: default is 0, i.e. hidden
 * * ``preferredHeight``: default is Kirigami.Units.gridUnit * 1.6
 * * ``maximumHeight``: default is Kirigami.Units.gridUnit * 3
 *
 * To achieve a titlebar that stays completely fixed just set the 3 sizes as the same
 *
