Simulates motion blur. We convolve the image with a Gaussian operator of the
given radius and standard deviation (sigma). For reasonable results, radius should be
larger than sigma. Use a radius of 0 and MotionBlurImage() selects a suitable radius
for you. Angle gives the angle of the blurring motion.
