Geometry Boost List: [geometry] Snapping vertices to line segments during intersections?

Does boost geometry have any functionality for snapping vertices to line segments during intersections?  For example if I have a large surface with vertices:

LargeSurface << (0,0) << (10,0) << (10,10) << (0,10)

And a smaller surface with vertices:

SmallSurface << (0+eps, 4) << (10,4) << (10,6) << (0+eps, 6)

I would like to define a tolerance where if abs(eps) < tolerance, the vertices of SmallSurface are projected to the edges of the LargeSurface.  Does that make sense?  Is there any good approach for doing this?

Thanks a lot,
Dan
