Blurs a matrix of the given width and height in-place by applying a horizontal blur of radius rx
and a vertical blur of radius ry (which defaults to rx).
The matrix values data are stored in a flat (one-dimensional) array.
If height is not specified, it is inferred from the given width and data.length.
Returns the blurred matrix {data, width, height}.
