code: function(other) {
      var temp;
      temp = other.id; other.id = this.id; this.id = temp;
      temp = other.width; other.width = this.width; this.width = temp;
      temp = other.height; other.height = this.height; this.height = temp;
    }
docs: ### .swapWith(other)  Switch this texture with `other`, useful for the ping-pong rendering technique used in multi-stage rendering.
