Function fz_clone_path 

pub unsafe extern "C" fn fz_clone_path(
    ctx: *mut fz_context,
    path: *mut fz_path,
) -> *mut fz_path

Clone the data for a path.

This is used in preference to fz_keep_path when a whole
new copy of a path is required, rather than just a shared
pointer. This probably indicates that the path is about to
be modified.

path: path to clone.

Throws exceptions on failure to allocate.
