+	flys/issue409 (Überschwemmungsfläche: Reihenfolge in Themenliste nicht immer synchron mit Rendering)
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java: Added
+	  a addLayer() method which should be used to add new layers to the map. New
+	  layers are always displayed at the bottom of the layer stack.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Use FloodMap.addLayer() to add new layers instead of adding them directly
+	  to the Map.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Removed the re-order process of map layers. This is no longer necessary,
+	  because MapOutputTab uses FloodMap.addLayer() to add new layers instead of
+	  adding new layers on its own using Map.addLayer() directly.
