const Matrix *in_mp,
This routine convolves the matrix pointed to by in_mp with a Gaussian mask
with the specified sigma, putting the result into *out_mpp. The mask
size is automatically chosen based on the value of sigma.
If *out_mpp is NULL, then an matrix of the appropriate size is created, if
it is the wrong size, then it is resized, and if it is the right size, the
storage is recycled.
The results near the boundaries are computed by assuming the input matrix
reflects itself at the edges.
NO_ERROR on success, and ERROR on failure, with an appropriate error
message being set.
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
