Detailed Description

Purpose:        Fast Computation of gaussian blurring.
                        Very useful for linear time scale space, Retinex, and linear time image blurrings.
                        Much faster than FFT on large kernels:  sigma >>> 0

                        Semi-Implicit solver using LOD multiplicative splitting
            (I - tau * A) * uNew=  uOld
