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.

Provide any channel constant that is valid for your channel mode. To
apply to more than one channel, combine channeltype constants using
