Dear Luke (& others),

Here's some test code, followed by the errors that I get when I try to 
compile it.  It boils down to some confusion about whether set is a 
type or a function.  Am I doing something that isn't allowed?  Thanks 
for any suggestions.

#include <boost/polygon/polygon.hpp>

template<typename COORD_T>
struct Box {
   typedef COORD_T coord_t;
   coord_t x0;
   coord_t y0;
   coord_t x1;
   coord_t y1;
};

typedef int screen_coord_t;
typedef Box<screen_coord_t> screen_box_t;

namespace boost { namespace polygon {

template <>
struct geometry_concept<screen_box_t> {
   typedef rectangle_concept type;
};

template <>
struct rectangle_traits<screen_box_t> {
   typedef screen_coord_t coordinate_type;
   typedef std::pair<screen_coord_t,screen_coord_t> interval_type;
   static inline interval_type get(const screen_box_t& rectangle, 
orientation_2d orient) {
     return (orient==HORIZONTAL) ? std::make_pair(rectangle.x0,rectangle.x1)
                                 : std::make_pair(rectangle.y0,rectangle.y1);
   }
};

}; };

typedef boost::polygon::polygon_90_set_data<screen_coord_t> markers_t;
markers_t markers;

void draw_marker(screen_box_t sb)
{
   using namespace boost::polygon::operators;
   markers |= sb;
}
