auto convolved(string axis, V)(const Image!V image, const real[] matrix)

Convolve a flat 2D matrix with a given center over an image and return the result.

With a matrix [0.5, 0.5] with width 2 and center [0, 0] convolved over an image each resulting pixel will be a 50:50 mix of itself and its right neighbour.
