C3D-0248 · 260714 Huckaby: fill the 17X11 title block and frame its viewport done

Copies the 13 title block attribute values from the 11X17 sheet onto the 17X11 sheet (same job) and points the landscape viewport at the same model view and scale as the portrait one, then locks it. Verifies every attribute and the viewport state on read-back.
