Shapefile and DBF constructors now support referencing files via both url and a HTML 5 File API handle. This can be used to load and map content added to file input(s) and processed on the client browser. FileReader and FileReaderSync are both used depending upon availability to make this functionality work in both Gecko and Webkit inside Web Workers.
