Duplicates an existing path, returning its index.

语法：

描述

This function takes a path and copies it into a new path. The new path is created in the process, and the index is returned to be used in all further calls to use this new path.

例如：

mypath = path_duplicate(choose(path_1, path_2, path_3, path_4));

The above code chooses one of four path resources and duplicates it, storing the index of the new path in the variable "mypath".
