<p>
The map includes two select feature controls. The first one operates on
geometries of type OpenLayers.Geometry.Point only and works on clicks. The
second one operates on geometries of type OpenLayers.Geometry.Polygon and
works on mouseover's. If you select the point geometry by clicking on it,
it shouldn't be unselected when the mouse moves out if it.
