SVG spec (http://www.w3.org/TR/SVG11/filters.html#feDisplacementMap) states that pixel values must be alpha-demultiplied before processing this filter operation. The following code does it, but when we DON'T do it, output is more similar to output from Batik.
Are you certain that our pixel values are premultiplied? I know we've problems in some places where they aren't where they should be, and vice-versa.
