            Mark more filter effect as alphaImage if possible
            https://bugs.webkit.org/show_bug.cgi?id=33111
    
            Mark more effects as alphaImage if the previous effect is a
            alphaImage. This can reduce the calculation on the next effect
            like feGaussianBlur.
    
            Test: This changes don't affect any LayoutTests and can't be tested
                  somehow, since the changes are 'invisible'.
