Annotorious Map Annotation

A helper plugin for using Annotorious with maps and geo-referenced images. After the
plugin is installed, annotation shapes will use geographic coordinates (latitude, longitude)
rather than image pixel coordinates.

This plugin currently works with Annotorious OpenSeadragon
and WMTS maps __only__.

The plugin depends on:
- OpenSeadragon
- Annotorious OpenSeadragon
- OpenSeadragon WTMS plugin

url: 'http://maps.wien.gv.at/wmts/1.0.0/WMTSCapabilities.xml'
});

// Initialize Annotorious
var anno = OpenSeadragon.Annotorious(viewer);
