I was wondering if there were an easy way to take a 2-D array
and create a new array of the same size/dimension but where
each pixel is the variance of some subset of itself and surrounding
pixels.

In other words, I'm looking for something akin to the SMOOTH
function but instead of doing a boxcar average, does a "boxcar
variance".
