The method to know if a vision or light source polygon could benefit from a fast triangulation was not working anymore.

[dev7355608]

What happened?

PointSource#_createPolygon/_createRestrictedPolygon doesn't have to return a ClockwiseSweepPolygon. If it doesn't, this.los.edges.size fails. los.edge seems to be always nonempty unless los.points is empty, which would mean that this check doesn't have any effect.

// LightSource#initialize

    // Compute the source polygon
    this.los = this._createPolygon();
    this._flags.renderSoftEdges &&= ((this.los.edges.size > 0) || (this.data.angle < 360));

// VisionSource#initialize

    // Compute the unrestricted line-of-sight polygon
    this.los = this._createPolygon();

    // Compute the constrained vision polygon
    this.fov = this._createRestrictedPolygon();

    // Render soft edges according to performances mode
    this._flags.renderSoftEdges = canvas.performance.lightSoftEdges
      && ((this.fov.edges.size > 0) || (this.data.angle < 360));

(_createRestrictedPolygon's return type should be PointSourcePolygon | PIXI.Polygon: the same as _createPolygon.)
