Hi Jason

Do we actually support anything other than MultiPolygons and Points? For my
GeoJson exporter, I default to MultiPolygon unless its a Point.

I have been able to successfully render all geojson using http://geojson.io

What is supported by GIS, I don't know, Jan would have to explain that.
