Subject: [PATCH] From Luc Frauciel, "osgUtil Tessellator : beginTessellation()
 made virtual to allow configuration of tessellation:

The initialisation of glu low level tessellator is done in  osgUtil::Tessellator::beginTessellation()
This function is not virtual, preventing any customization of the tesselation.
In particular, there in an option in glu tesselator that force the generated primitives to be triangles and that I'd like to use (GLU_TESS_EDGE_FLAG).
