I have checked the FAQ and poked around the suggested FTP sites and have
not come up with a
Gaussian Blur function (in 3D)
along the lines of smooth() which uses a uniform kernal instead of a
Gaussian one.

I still can't believe that this isn't part of the standard library; I
have tried smooth2(), which LOOKS fine, but it is only "approximately"
Gaussian, which doesn't cut it (try writing a methodology section of a
medical imaging paper saying you used "approximately" gaussian
smoothing).

A valid respons would be: DIY! Yes, I am working on a function that
uses Gaussint() to make a kernal to convolve with convol(), but I hate
reiventing the wheel when I know someone else MUST have had this exact
same need.
