    Floating Point Exception in FEConvolveMatrixSoftwareApplier:: applyPatform
    https://bugs.webkit.org/show_bug.cgi?id=248288
    rdar://102137760

    There is a division by zero due to the fact that sometimes there is one variable much bigger than other that are implied in a division (clipBottom and iterations) and as c++ rounds down it is consequently zero, which leads to the subsequent exception.
