      Description

      I'm seeing artifacts along patch boundaries in difference images, anywhere a source falls exactly on the boundary. My guess is this is caused by the model at the edge of the patch being cut off right at the bounding box, and then shifted for DCR. The DCR shift should be applied first to a larger region with a buffer of several pixels around the edges, and only trimmed to the bounding box later.

          Could you please take a look at these changes in ip_diffim? It's a fairly small change, and fixes a bug in image differencing when using a DcrModel as a template.
