Re: [OpenMap Users] Gathering the extents or average area covered

Hi Erich,

The ShapeLayers implement the DataBoundsProvider interface, which
provide the extents of their data. The CSVTiledImagePlugIn doesn't
implement that interface, but it could.

There's a DataBoundsViewMenuItem that uses the MapHandler to find
DataBoundsProviders, and lets you zoom in over a layer's data if they
provide that information.
