I'd also like to see a perf test for gaussian blur in general, not only for this patch.

Did your last patch still cause some pixel differences? Alex and others spend a lot of time in making FEGaussianBlur as compatible and comparable  as possible with other viewers. Would like to know if the difference is noticeable.
Even so, can you update the pixel results please?

PS: Thanks for working on filters :-).
