[boost] [gil][ublas] Point2DConcept and ublas vector concept

Hi, I'd like to use my boost::ublas::bounded_vector types interchangeable with boost::gil::point2 which from my point of view makes totally sense: A convex hull algorithm for 2D would only need to be implemented once (for world coordinates and pixel coordinates) for example. This, however, seems impossible right now because of the differences in their concepts. Is it possible to somehow make a bridge between them (without copying structures)? Any plans to unify those concepts and reuse ublas types? Best regards, Christoph
