◆ Initialize()

void b2WorldManifold::Initialize	(	const b2Manifold *	manifold,
		const b2Transform &	xfA,
		float	radiusA,
		const b2Transform &	xfB,
		float	radiusB
	)

Evaluate the manifold with supplied transforms. This assumes modest motion from the original state. This does not change the point count, impulses, etc. The radii must come from the shapes that generated the manifold.
