SVGGen and filters

First, Hi all and thanks for this great product .

I'm doing some stuff using SVGGraphics2D and SVGGen, everything is great
until I want to use filters. I really don't want to use batik image
generated by svggen.

for example, what should I do to get a simple drop shadow ?

<svg width="200" height="200" xmlns="http://www.w3.org/2000/svg" >
     <defs>
          <filter id="filter" filterRes="100" x="0" y="0">
               <feGaussianBlur stdDeviation="4 4"/>
               <feOffset dx="4" dy="4"/>
          </filter>
     </defs>
     <rect x="4" y="4" width="100" height="100" fill="grey"
filter="url(#filter)"/>
     <rect x="0" y="0" width="100" height="100" fill="blue" stroke="black"/>
</svg>

I found many java code that will achieve that but they are all very
complected and they use BufferdImage (that will end up to be hard coded
image in the SVG source). 

I also want a way to have it both-ways, in java and exporting it to SVG. 

Any idea ?

   The concept of filters goes well beyond what the Graphics2D
interface can accommodate so you will need to get the group that
you want filtered (via 'SVGGraphics2D.getRoot()') and then
add the filter stuff. 

   You will need to create the filter elements 
with Document.createElementNS, set the various attributes on those
elements with 'setAttributeNS', and add the filter attribute to
the group from getRoot, and finally append them both to your
final document (which you will need to manage yourself).
