clipper2's Issues

Support for geo-types

Hi, cool project!

I discovered this when searching for Rust bindings to Clipper 2. I'm stuck on Clipper 1 via geo-clipper which uses a five year-old version of the library, and while it works I'm curious to see if Clipper 2 is more numerically robust.

One thing I'd like to see is integration with geo-types since my code is already using these types all over the place, and I might (at some point) send a PR for this myself if you'd be open to it.

Memory leak and unessessary copy

For example impl From<Polygons> for PolygonsC

1. Clones the entire content of Polygon instead of transmuting the pointer to the vec 👎
2. Never cleans up the memory 👎

Both of these are solved if the for example Polygons owns the data and PolygonsC is only a c pointer reference into Polygons so we dont need to do any memory cloning, and this makes rust clean up the memory. This assumes that all the c types are private, as PolygonsC must never outlive Polygons if this is the case.

Examples?

There is no example folder for examples on how to use the API
