Memory leaks when using GaussianBlur or BoxBlur

[yangqingren]

override func viewDidLoad() {
    super.viewDidLoad()
    self.runFilter()
}

func runFilter() {
    
    let testImage = UIImage(named: "WID-small.jpg")!
    let blur = BoxBlur()
    let filteredImage = testImage.filterWithOperation(blur)
    
    DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
        self.runFilter()
    }
}
