The Polygon3 branch now includes an implementation of the Douglas-Peucker algorithm for line simplification by reducing the number of points. It is already included in the repository and will be part of the next release.
Now that python 3.3 is out I decided to focus much more on python-3. This has some impact on my development of python modules. Bugs in the Polygon2 branch (for python 2.x) will be fixed in the near future but new features will only be implemented in the Polygon3 branch.
