Thank you David. If it's as you say, I think I can use Node.getBounds upon
insertion to find the initial coordinates. From that I can make a vector3D
and store it aside. Then I can use the transform itself to see how much
the object has been translated. Put that translation factor in a vector3D.
Then a vector addition should give me the correct coordinates!
That was all I needed to add my final little feature in my project. I knew
there must exist a way to do it. I had thought of the transform3D for the
translation vector but just didn't know how to get the initial coordinates!
Thank you very much guys!
