I admit that GTL is not a generic geometric library, it has limited
scope.
It is limited to rectilinear geometry, fixed precision. It took us years

of development, refinement and brutal testing to get where we are.
Certainly there is much more geometry out there, math has no boundaries.

Our internal name is GTL and was using that name.
Our main target is to make it available on boost and facilitate its
adoption
in other libraries. We are certainly open to suggestions and feedback.
