/**
* The {@link TitleBar}'s layout manager.
* This class makes sure the minimum dimension of the title bar is always
* {@link TitleBar#MIN_WIDTH}x{@link TitleBar#HEIGHT}.
* This is possible because the title bar has a <code>null</code> UI delegate
* and its dimensions are never set. So every call to a <code>getXXXSize</code>
* method will eventually be answered by this class'
* {@link #minimumLayoutSize(Container) minimumLayoutSize} method.
* The layout assumes the title bar has no borders.
