They were meant to support lowres pixel-art by using postprocessing shaders which were specifically created for this style.
, yes I know, no misconception. Maybe bad wording on my part grin. I quess with pixel art I personally think more about extreme pixelated games. Maybe not the best example but oh well;

Still good job on the shader.

I personally like this style more (sort of high reso pixels and no jagged edges): http://media.edge-online.com/wp-content/uploads/edgeonline/2013/04/RidiculousFishing.jpg
