edge compositing test

Two of almost the same filter chains depicted.
One blends the source image atop itself, the other eliminates alpha channel first, blends that above eachother the same way, and finishes with a composite:in at the end.
Note the difference in the transparencies of the objects, and also how the edges are rendered differently with the anti-aliasing.
