Hm... a posibility is to apply the last patch of
https://bugs.webkit.org/show_bug.cgi?id=28133 replace getImageData with
getPremultipliedImageData() and putImageData with putPremultipliedImageData(),
build with --filter enabled and look at
http://www.w3.org/Graphics/SVG/Test/20061213/htmlObjectHarness/full-filters-blend-01-b.html
(ignore the first line, it's a bug in the filter implementation).

Sorry, I know that this is a bit complex just for testing, but it was a
preperation for SVG filters.
