Is it worth to mention that approximation is very accurate?

Instead of "very accurate" I prefer to give a notion of the accuracy. In this case it depends on a few variables so I put in the link in the C header.

GaussianBlurisradius. The canonical name for the parameter is standard deviation. The value for the standard normal distribution at a given radius is a function of standard deviation.GaussianBlurdoesn't convolve the image with a Gaussian kernel. It uses a kernel that when applied iteratively approximates a Gaussian kernel.The changes improve the precision of the documentation.
