The #GtkTreeIter is the primary structure
for accessing a #GtkTreeModel. Models are expected to put a unique
integer in the stamp member, and put
model-specific data in the three user_data
members.
Creates a dynamically allocated tree iterator as a copy of iter.
This function is not intended for use in applications,
because you can just copy the structs by value
(GtkTreeIter new_iter = iter;).
You must free this iter with gtk_tree_iter_free().
