addnoise adds noise from the noise image to the input image.
The noise image tiles the input image. The magnitude of the noise is scaled
by a floating point magnitude mag. It’s range is [0.0 ... 1.0]. 0.0 adds no noise
into outimage, while 1.0 add alot of noise. Typicaly randimg is used to create
a noise pattern (histeq can also be used).
