I have made a major performance update! The CSG engine has bee, where possible, accelerated using the OpenCL bindings provided in Aparapi. If you have OpenCL instaalled on your system, then Manifold export and the Core CSG operation splitPolygon will be accelerated on the GPU automatically. If you do not have OpenCL, then it will default back to a thread pool architecture.
