Issue DM-4858: imagesDiffer doesn't handle overflow for unsigned integers
I'm seeing a test failure in afw's testTestMethods.py, apparently due to my numpy (1.8.2) treating images that differ by -1 as differing by 65535 in both {{numpy.allclose}} and array subtraction (which doesn't promote to an unsigned type). Does this still cause problems in more recent versions of {{numpy}}? If not, I imagine it's up to me to find a workaround for older versions if I want it fixed? (assigning to [~rowen] for now, just because I know he originally wrote this test and I hope he might know more)
