C3D-0252 · 260714 Huckaby: point the 17X11 viewport at the property done

C3D-0251 copied the paper background pseudo-viewport instead of the real one, leaving the landscape viewport at 1inch=1foot on sheet coordinates. Sets it explicitly to the 11X17 sheets view: center 1036448.40,465018.49 at customScale 0.030776 (1inch=32.49feet), on and locked. Distinguishes the real viewport from the background by whether its view center is in model coordinates.

C# payload

// C3D-0251 read viewport #1 (the paper background pseudo-viewport) instead of the real one,
// because after switching the current layout the iteration order changed. Set the 17X11
// viewport explicitly to the known-good view from the 11X17 sheet:
//     center (1036448.40, 465018.49), customScale 0.030776  => 1" = 32.49'
