<p><b>pamgauss</b> generates a one-plane PAM image whose samples are a
gaussian function of their distance from the center of the image.  I.e.
the sample value is highest in the center and goes down, in a bell curve
shape, as you move away from the center.

<p>The values are scaled so that the area under the surface of the
two-dimensional Gaussian function is the maxval of the image.

<p>You can use this image, converted to PGM, as a convolution kernel
with <b>pnmconvol</b> to blu
