                an out-of-tree group of paths is generated for each text story converted to outlines.

                This list allows the group of paths to be generated once during the export process
                (instead of once for calc of file size, then again for actual output)
                It also allows the paths to exist for the entire export lifetime, so that the paths
                can safely be used during export for other processes (such as the smart path similarity
                code that detects paths that differ only by a transformation).
