[cairo] Premultiplied transparency causes streaks in images

[Paril]

Hmm, well it looks interesting, not a big fan of graph-based processing
though, the API just seems like a front to put together the XML data and
then compile it. I was more or less looking for something just like Cairo
where I can.. draw things rather simply. It's surprising that I can't seem
to find anything for this already. The C# binding for GEGL, I can't even
find the .cs files in the git root..

I'll keep looking I guess.

-P
