28 The smearing works like this: First, assume a grayscale
29 image. For each pixel in the image, __pamoil__ looks at a
30 square neighborhood around it. __pamoil__ determines what
31 is the most common pixel intensity in the neighborhood, and
32 puts a pixel of that intensity into the output in the same
33 position as the input pixel.

36 For color images, or any arbitrary multi-channel image,
37 __pamoil__ computes each channel (e.g. red, green, and
38 blue) separately the same way as the grayscale case
39 above.

42 At the edges of the image, where the regular neighborhood
43 would run off the edge of the image, __pamoil__ uses a
44 clipped neighborhood.
