The WebKit [implementation](https://github.com/WebKit/webkit/blob/master/Source/WebCore/platform/graphics/filters/FEComposite.cpp) of this filter is rather complex. Nothing close to `k1*i1*i2 + k2*i1 + k3*i2 + k4`. And they use premultiplied ARGB, just like librsvg and Inkscase.

Maybe its because of some optimizations.
