    This is used in z2 to limit the number of pixels over which the
    filter is applied, as per "numPx" in 7.11.2.4 point 4 in the AV1
    specification. This only applies to z2, because in z1/3, the edge
    filter is (incomprehensibly) lengtened by the opposite side's edge
    length, which undoes the limit on the filter length (like a bug
    undoing another bug).
    
    I admit the code is getting rather complex, so we may want to
    redesign this to make writing SIMD easier.
