name: Structure coordinate offset propagation
author: Karl Ostmo
description: |
  If a structure incorporates subplacements
  entailing negative offsets, its coordinate origin must be shifted.

  The updated coordinate origin should be propagated to parent structures
  and utilized to offset placement.
