    perf: Test gegl:gaussian-blur's IIR filter
    
    The infinite impulse response (IIR) filter is more interesting for
    performance testing because that's what's used for most standard
    deviation values, which is anything that's not too small. The current
    threshold is 1.0.
    
    By default, operations like dropshadow and shadows-highlights use the
    IIR filter, and most optimization efforts in the literature are
    targetted towards it. In case there is a specific need to track the
    performance of the FIR filter, it can be added later.
