This library comes in three implementations: Delphi, C#, C++.   That's
_not_ bindings to a common library but three seperate implementations.

And there are further contributed implementations:  Flash Go Haskell Java
LuaJIT Matlab ObjectiveC perl python ruby.

I wrote (incomplete) Python bindings to the C++ implementation, to see
if that can be used for DRC. 

The library works on integer polygons and uses 128bit integers
internally.
