[gtk/wip/ottie/print: 8/45] path: Rename to gtk_path_builder_add_segment()

[Matthias Clasen <matthiasc src gnome org>]

commit a2671b4472cad027d58bd367d3a41affc090fad5
Author: Benjamin Otte <otte redhat com>

    path: Rename to gtk_path_builder_add_segment()
    
    It's about bulding paths, not about measuring them.
