Accepts any geometry -- point, line, polygon, or a collection of them, each buffered about its own centre latitude -- and answers with a Feature, or a FeatureCollection when you sent several. A buffer that collapses (a negative distance larger than the shape, or any negative distance on a point or a line) answers geojson:null with empty:true, which is an answer and not an error.
