<h1>GeoGraphics</h1>
<p> GeoGraphics are graphical objects, that does not store the graphics information
in screen space, but in geographical coordinates. Therefore GeoGraphics must be
placed on GeoLayers to work properly. </p>
<p><i>
Note: As GeoLayers are always children of a map layer. When the map is changed
all GeoLayers are notified via the 'adaptTo(map)' method.</i></p>
<p>
The geolayers forward this 'adaptTo' to all children that are GeoGraphics.
Which adjust their so called 'point' data to the new map.</p>
</ul>
