2.0 uses a altered 2.0 version of it, shares a lot with it.
2.0 uses an altered version of the Luminous Engine. As far as I know and observed, FF16 appeared to use it too.

Whether it borrowed any code from Crystal Tools, I can't say because I haven't worked with any of these... but they are supposed to be completely separate engines and that was the supposed to be the entire point of switching.
