- updated to clipper version 6.1.3a
- clipper_polygons_offset is using the deprecated OffsetPaths function instead of the newer ClipperOffset class. This will need to be changed at some point.
- added clipper:get_bounds_real() for real this time
- clipper changed the terminology from "Polgyon" to "Path". However, the ffi bindings API has not changed.
- changed clipper.tonumber to clipper.toreal
