Consider the following GVT node tree:

	      +----+
	      | N1 | BKGRND = new
	      +----+
                /\
	       /  \
	      /    \
         +----+   +----+    
	 | N2 |	  | N3 | Opacity=0.5
	 +----+	  +----+
          /|\       |  \
         .....      |   \
                    |    \
                  +----+ +----+
		  | N4 | | N5 | Filter = feOffset(src=Background)
		  +----+ +----+


N1.paint(G)
  Calls N2.paint(G)
  N2.paint does it's thing...
