Geometry Boost List: [ggl] Polygon, points and accessing elements

Hello list,

I'm using now the polygon template to construct several polygons on a
groundware simulation. But I need to, given one point, access the previous
and the nex point, for each point in the polygon. Is that possible? Also, it
seems that ggl is getting a lot of changes now. Could basic structures, like
point_2d, polygon_2d and the access methods change?

I would consider changing all the coordinates and geometric elements in my
simulation to ggl if it's possible to access the coordinates in the polygon.

Thanks again

Ivan Marin
