Yup this gets rid of the warning

I changed the code to only pad each region by 1 pixel in each direction
and communicate the boundary pixel values at each iteration. The runtime
dropped to 19 minutes, and the ram used was a little less. It should
make the number of iterations unlimited ( no more excess padding soaking
up RAM ).

I'll have to run a test on a small image to see if everything works when
compared to regular Vector Gradient Anisotropic Diffusion.
