Hi,

We would like to ask for a formal review for the Generic Geometry 
Library (GGL).

The GGL defines concepts for geometries and implements some algorithms 
on such geometries.

GGL contains a dimension-agnostic, coordinate-system-agnostic and 
scalable kernel,  based on concepts, meta-functions and tag-dispatching. 
On top of that kernel, algorithms are built: area, length, perimeter, 
centroid, convex hull, intersection (clipping), within (point in 
polygon), distance, envelope (bounding box), simplify, transform, 
convert, and more. The library is also designed to support high 
precision arithmetic numbers, such as GMP.

GGL contains instantiable geometry classes, but library users can also 
use their own. Using registration macros or traits classes their 
geometries can be adapted to fulfil the GGL-concepts.

The GGL might be used in all domains where geometry plays a role: 
mapping and GIS, gaming, computer graphics and widgets, robotics, 
astronomy... The core is designed to be as generic as possible and 
support those domains. However, for now the development has been mostly 
GIS-oriented.

We propose the extension model, the same way as GIL also applies it. So 
we are going to help to organize development of GGL extensions, where an 
extension is (mostly) something more specific to domains like mentioned 
above.

The proposed  GGL has seen four previews, many discussions and many 
changes in design and implementation, based on those discussions. The 
last preview was in February '09. Since then the design of the library 
is stable and the library contains a variety of coherent functionality. 
So we feel that the library is matured enough for formal review.

Therefore, I would like to request a formal review and the library 
placed into the review queue. It is put into the Boost.Sandbox:
https://svn.boost.org/svn/boost/sandbox/ggl/formal_review_request

We have a review manager.
