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