C3D-0279 · 260714 Huckaby: real extents excluding origin junk, and boundary size done

READ-ONLY. Logs the drawing filename for proof, measures model extents ignoring anything at (0,0), reports the scale needed to fit the 16.34x10.34 border and a table of standard scales, and lists every closed boundary polyline with area.
