Blur the image by setting each pixel to the average value of the pixels
in a square box extending radius pixels in each direction.
Supports float radius of arbitrary size. Uses an optimized implementation
which runs in linear time relative to the size of the image
for any radius value.
:param image: The image to blur.
:param radius: Size of the box in one direction. Radius 0 does not blur,
returns an identical image. Radius 1 takes 1 pixel
in each direction, i.e. 9 pixels in total.
:return: An image.
