int32 b2ClipSegmentToLine	(	b2ClipVertex	vOut[2],
		const b2ClipVertex	vIn[2],
		const b2Vec2 &	normal,
		float32	offset,
		int32	vertexIndexA
	)

Clipping for contact manifolds.

void b2GetPointStates	(	b2PointState	state1[b2_maxManifoldPoints],
		b2PointState	state2[b2_maxManifoldPoints],
		const b2Manifold *	manifold1,
		const b2Manifold *	manifold2
	)

Compute the point states given two manifolds. The states pertain to the transition from manifold1 to manifold2. So state1 is either persist or remove while state2 is either add or persist.

bool b2TestOverlap	(	const b2Shape *	shapeA,
		int32	indexA,
		const b2Shape *	shapeB,
		int32	indexB,
		const b2Transform &	xfA,
		const b2Transform &	xfB
	)

Determine if two generic shapes overlap.
