* layout handling will be delegated to the class LayoutHelper which can be accessed by
* getLayoutHelper. There are some layout helper methods in this class which will be
* exist some time longer, but they are deprecated. At a redesign or new panel use the layout
* helper. There is a special layout manager for IzPanels. This layout manager will be supported by
* the layout helper. There are some points which should be observed at layouting. One point e.g. is
* the anchor. All IzPanels have to be able to use different anchors, as minimum CENTER and
* NORTHWEST. To use a consistent appearance use this special layout manger and not others.
