It's a destructive operation and it won't necessarily give the results one'd
wanted. Filter layer applies the filter only once, to the projection of all
layers below it. The only reliable way to get the same results is to merge
everything below and apply the filter. In this case, it would be first applying
the filter to every single layer, and then calculate the projection. Different
order of operations means different math, different result.
You can check it with two rectangles that are so close together that there is
no gap between them, but they're on different layers, and apply the Blur filter
with 100 px. In case of filter layer on top, they will be nicely blurred. In
case of applying filter to both separately, there will be a weird blurred gap
between them.
Maybe it should be implemented as a Python plugin?
