The function ImageEffect allows to add noise to an image, however the
options are very limited: only uniform, Gaussian and salt&pepper. I
need to add Poisson noise. it should be straitforward to to create
that filter by modifying the Gaussian, but I am not bale to find any
documentation.

Anybody out there with a clue?
