I've noticed that the "smooth" filter in the example patch for
[pix_convolve] has a wrong scale factor which results in a slightly
darker output image than the input.
I don't know much about convolution filters, but the number being bassed
to [pix_convolve] seems right to me: 0.0625 which is 1/16, and it seems
right since the sum of the coefficients is 16.
Is the number being passed as scale factor in the help patch wrong, or
is there a bug in [pix_convolve]?
Or is this the expected result in a way I don't see?
