     * There are two different layer types:
36
     *  - MapLayer: Displays Maps, but also Geometries. The configuration for displaying maps have to be done in the MapAdapter
37
     *  - GeometryLayer: Only displays Geometry objects.
38
     *
39
     * MapLayers also can display Geometry objects. The difference to the GeometryLayer is the repainting. Objects that are
40
     * added to a MapLayer are "baken" on the map. This means, when you change it´s position for example the changes are
41
     * not visible until a new offscreen image has been drawn. If you have "static" Geometries which won´t change their
42
     * position this is fine. But if you want to change the objects position or pen you should use a GeometryLayer. Those
43
     * are repainted immediately on changes.
