Message:

Soften errors, both in the least-squares matrix/vector construction and in the rejection stage. Softening in the rejection stage seems to be very important so that bright stamps aren't rejected (after which the solution can go crazy). Now carrying around a weight image = 1/variance instead of the variance image. This can be softened, saving many divisions in the matrix/vector construction.
