* An item that can be used as a title for the application.

* the minimum, preferred and maximum heights of the item can be controlled with
* * minimumHeight: default is 0, i.e. hidden
* * preferredHeight: default is Units.gridUnit * 1.6
* * maximumHeight: default is Units.gridUnit * 3
*
* To achieve a titlebar that stays completely fixed just set the 3 sizes as the same
