liquidfun 1.1.0 (new formula)

LiquidFun is a 2D rigid-body and fluid simulation C++ library for games
based upon Box2D.
It provides support for procedural animation of physical bodies to make
objects move and interact in realistic ways.
I'm not sure. As I know this library make deep copy of Box2D and extend it.
It's possible that box2d will have new version but liquidfun still  use older one.
I do not participate in the development of this library. I just use it.
