Here is the zip file containing the patches for this RFE, I made very few
modifications (mostly transformations from private to protected for some
methods), to the following classes :
- AbstractGraphics2D in org.apache.batik.ext.awt.g2d
- DOMTreeManager, DOMGroupManager, SVGGraphics2D in org.apache.batik.svggen

I rebuilt the whole Batik jars after this change, and after subclassing
SVGGraphics2D, DOMTreeManager, and DOMGroupManager in my client application,
I was able to control the structure of the generated SVG Tree.

As you requested, I provided in SVGGraphics2D a protected setter for
DOMGroupManager and DOMTreeManager.
Hope it is the good patch format (diff -u), as I'm not a cvs guru at all. In
fact, I had much more problem in generating the patch files than for all the
rest ;)
