/**
 * @class   vtkGeoView2D
 * @brief   A 2D geospatial view.
 *
 *
 * vtkGeoView is a 2D globe view. The globe may contain a multi-resolution
 * geometry source (vtkGeoTerrain2D), multiple multi-resolution image sources
 * (vtkGeoAlignedImageRepresentation), as well as other representations such
 * as vtkGeoGraphRepresentation2D. At a minimum, the view must have a terrain
 * and one image representation. By default, you may select in the view with
 * the left mouse button, pan with the middle button, and zoom with the right
 * mouse button or scroll wheel.
 *
 * Each terrain or image representation contains a vtkGeoSource subclass which
 * generates geometry or imagery at multiple resolutions. As the camera
 * position changes, the terrain and/or image representations may ask its
 * vtkGeoSource to refine the geometry. This refinement is performed on a
 * separate thread, and the data is added to the view when it becomes available.
