* A simple map container that is a JPanel with a map in. provides simple |
|
|
* pan,zoom, highlight and selection The mappane stores an image of the map |
|
|
* (drawn from the context) and an image of the slected feature(s) to speed up |
|
|
* rendering of the highlights. Thus the whole map is only redrawn when the bbox |
|
|
* changes, selection is only redrawn when the selected feature changes. |
