Description
By default, simplify() does not preserve topology - e.g. polygons can be split, collapse to lines or disappear holes can be created or disappear, and lines can cross.
The attached patch adds a preserve_topology parameter. If True (default is False), the result will have the same dimension and number of components as the input. This is significantly slower.
