a red-black wavelet kernel

check-up the kernel I've calculated recently; It's high-pass kernel for
first step of red-black wavelet transform; to test it - just put it into a
any graphics program with 7x7 custom matrix filter capatibility
(PaintShopPro will do) and type it. The more gray image becomes -> the more
signal was removed

matrix:
[ [0,-4, 0,6,0,-4,0]
  [-4,0,13,0,13,0,-4]
  [0,13,0,-88,0,13,0]
  [6,0,-88,256,-88,0,6]
  [0,13,0,-88,0,13,0]
  [-4,0,13,0,13,0,-4]
  [0,-4, 0,6,0,-4,0]]

it behaves very good on all standard test images (including lena, alu,
arctic_hare, baboon, bear, peppers, texmos1.p512, water and z1x25)
