You are talking about things such as convolution with a defined kernel
size. There are other operations and a compositor truly transforms an
image to another image and not pixels to pixels etc. If it's
implemented in such a naive way, the compositor will be very limited.
I got a very bad feeling about this....

Ok, let's normalize an image with a tile based approach,... uh damn it....
