Detailed Description

A data structure for holding a path.

Use Context::copy_path2() or Context::copy_path_flat2() to instantiate a new Path.

If you use the deprecated Context::copy_path() or Context::copy_path_flat() to instantiate a new Path, the application is responsible for freeing the Path object when it is no longer needed.

To access the path data, use begin() and end() or cbegin() and cend() to iterate through the Path Elements
