Adding a pixelate node.

This makes it possible to create pixelized scale in the Tile compositor.

Just append the node in front of a scale node or where you want the pixelization to take place.

There were some bugs on this subject, but they used the work around to add a blur size of 0 in the place where they need the pixelization.
