        Nbody broken when cl-gl interop is off (e.g. CPU)
        #342

        Reviewed by TrustMe.

        Nbody fails with a TypeError exception because Context::createCommandQueue
        is StrictTypeCheck'ed. JS was passing a device vector, while implementation
        expects a device object.

        It did not affect when cl-gl is ON (e.g. GPU) because CLGLContext::createCommandQueue
        were not StrictTypeCheck'ed (oops!).
