C3D-0268 · 260714 Huckaby: resize the SS_BLOCK_17X11 DEFINITION to 16.34 x 10.34 and seat it 0.33 inside the paper done

Stops fighting the insert scale factors. Rewrites the block definitions coordinates directly - Line endpoints, DBText/AttributeDefinition Position+Height+WidthFactor, MText Location+Height+Width - to compress it to exactly 16.34 x 10.34 about its right-bottom corner. Direct coordinate rewriting works where non-uniform TransformBy is rejected. Then resets the insert to 1:1 and seats it so all four insets are 0.33.

C# payload

// Stop fighting the insert. Reset the block reference to 1:1 at a known point, then edit the
// DEFINITION so the border is exactly 16.34 x 10.34 and everything inside is repositioned to
// match. That is the only way to get all four insets exact.
//
// Plan:
//   1. reference back to scale 1,1 at insert (16.67, 0.33)  -> definition x=0 lands at x=16.67,
//      so definition coords map to sheet as: sheetX = 16.67 + defX, sheetY = 0.33 + defY.
//      For a border 16.34 wide ending at sheet 16.67, the definition must span defX -16.34..0.
//   2. measure the definition's real extents, then scale its CONTENTS about the origin so it
//      becomes exactly 16.34 x 10.34. Non-uniform TransformBy is rejected for Line/Text, so do
//      it by rewriting coordinates directly: Line endpoints, text Position/Height, attribute
//      Position/Height. That works where TransformBy will not.
