Re: Compositing math in SVG

I think I have found a problem with Photoshop blend modes or
the SVG spec.

I implemented ColorBurn as specified here:

http://www.w3.org/TR/SVGCompositing/

Here is a test I made:

And here is what I get in Photoshop, notice the extra
red pointed by the arrow:

That red must be an error, there is no red there
in any of the input images. Here are the two images
I blend:

In this case I think it is an issue in Photoshop,
what do you think?
