I don't have much experience with geometry libraries, but looking at the 
concept diagram for gtl made me curious if symmetry concepts could be 
integrated in a useful way into the library.  That is, some kind of mapping 
onto planar symmetry groups:

http://en.wikipedia.org/wiki/List_of_planar_symmetry_groups

which at least takes advantage of basic rotational and reflection symmetries.  
- From my naive point of view, it seems like knowing the symmetry of a polygon 
could be useful when operating on it.  I do see a section on isotropy, and 
there is a Rectangle concept, but I don't see anything that could take 
advantage of the symmetry of, say, an equilateral triangle.

Maybe the above isn't relevant to Boost.Polygon though, as I'm having 
difficulty telling what the library does from the online docs.  A full 
tutorial instead of just a list of commented example code files might help 
new users a lot.  Also, I cant find any documentation on what the names of 
the library's header files are or what they each contain.
