    csg2d.js

    A 2D port from CSG 3D library

    largely inspired by https://github.com/evanw/csg.js

    Usage

    var subjectPolygon = CSG.fromPolygons([[[10, 10], [100, 10], [50, 140]]]);
    var clipPolygon = CSG.fromPolygons([[[10, 100], [50, 10], [100, 100]]]);
    // note: this syntax is also accepted
    // var clipPolygon = CSG.fromPolygons([[{x:10, y:100}, {x:50, y:10}, {x:100, y:100}]]);
     
    var subtractPolygons = subjectPolygon.subtract(clipPolygon).toPolygons();
    var unionPolygons = subjectPolygon.union(clipPolygon).toPolygons();
    var intersectPolygons = subjectPolygon.intersect(clipPolygon).toPolygons();
     
    /*
    return [
      [ {x:x1, y:y1} , ... , {x:xN, y:yN} ], //polygon #1
      ...
      [ {x:x1, y:y1} , ... , {x:xN, y:yN} ], //polygon #K
    ]
    */
