    Create a default frame if missing from template file
    
    When parsing a template node, if there is no recognized frame node (e.g.
    Label-rectangle), a default full-page frame with a 1x1 layout is created.
    This prevents potential crashes if sharing a user '.glabels' directory
    with future versions of glabels with new frame types, or in the case of
    typos for hand generated templates.
