This matrix is the inverse of the original block reference (insert entity) transformation. The original block reference transformation is the one that is applied to all entities in the block when the block reference is regenerated (always 12 entries). 40 4x3 transformation matrix written out in column major order. This matrix transforms points into the coordinate system of the clip boundary (12 entries).
