// rationale:
// this is conceptually a different kind of path, not a superset of VfsPath,
// hence NativePath instead of Path (PathUtil is a bit clunky as a
// namespace anyway).
// a typedef instead of wrapper class avoids the need for accessor functions
// (e.g. boost::filesystem::string()) at the cost of somewhat diminished safety.
// users are responsible for ensuring the path doesn't contain any forbidden
// characters (including any code points >= 0x100 on anything but Windows)
