Hello,

I just wonder whether while CGAL has a snap rounding, which works on segment
(http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Snap_rounding_2/Chapter_main.html),
is there a polygon snap rounding, that works on polygon?

The reason I ask this is because I have a lot of polygons I import from a
drawing, these polygons represent entities that mustn't overlap, and can
only touch ( think about countries on a map), but due to a lot of rounding
errors, I can't retrieve the topological relationship between the polygons
directly ( the polygons may slightly overlap, two polygons that should be
adjacent to each other may have small gaps in between them, etc). So I would
need to somehow "round" them.

What do you think?
