Just rotation...

That might be... now that you ask me... the vecmath library comes from the 
Java3D packages... and I have such installed in my 1.4.0 installation...

That jar I have also in the classpath... but I guess the Java3D vecmath gets

We can not expect people to deinstall Java3D, so we must find another way to 
solve this...
