Compares each image with the next in a sequence and returns the minimum
bounding region of all the pixel differences (of the ImageLayerMethod
specified) it discovers.
Images do NOT have to be the same size, though it is best that all the
images are 'coalesced' (images are all the same size, on a flattened
canvas, so as to represent exactly how an specific frame should look).
No GIF dispose methods are applied, so GIF animations must be coalesced
before applying this image operator to find differences to them.
