// SVGPathSeg API polyfill
// https://github.com/progers/pathseg
//
// This is a drop-in replacement for the SVGPathSeg and SVGPathSegList APIs that were removed from
// SVG2 (https://lists.w3.org/Archives/Public/www-svg/2015Jun/0044.html), including the latest spec
// changes which were implemented in Firefox 43 and Chrome 46.
//
// Example API usage:
// var path = document.createElementNS("http://www.w3.org/2000/svg", "path");
// var moveToSeg = path.createSVGPathSegMovetoRel(10, 10);
// var lineToSeg = path.createSVGPathSegLinetoRel(100, 100);
// path.pathSegList.appendItem(moveToSeg);
// path.pathSegList.appendItem(lineToSeg);
// console.log(path.getAttribute('d')); // m 10 10 l 100 100
// moveToSeg.x += 200;
// moveToSeg.y += 200;
// console.log(path.getAttribute('d')); // m 210 210 l 100 100
