I want to paint a SVG directly on a Graphics2D, without creating first a BufferedImage.
Therefore I used the GraphicsNodes paint()-method. But it doesn't work with SVGs using
filter - the result looks ugly. Using the StaticRenderer instead works fine, but
I don't want to use that. Why doesn't it work?

Hi Guys,
The problem is that the component doesn't have an alpha channel.
So when the filters try to match it the result is pretty ugly. I have
attached a tentative patch for the problem. I'm wary about putting it
in CVS because this stuff evolved out of a lot of trial an error, so
any change is really risking breaking stuff that already works...
I want to at least have a chance to check printing before I
commit the change.
