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.
