Description Brian Salomon 2011-12-07 13:47:57 PST
This can be demonstrated by running the svg/dynamic-updates/SVGFEDropShadow* layout tests with an assert that r, g, and b are <= a in an implementation of ImageBuffer::putPremultipliedImageData. 

The call to putPremultipliedImageData is here: http://trac.webkit.org/browser/trunk/Source/WebCore/platform/graphics/filters/FEDropShadow.cpp#L108
