subsurface: Update position of comp object upon creation

Upon creation, the position of the comp object for a subsurface must be
updated to ensure that the subsurface is positioned correctly based on
its ancestral relationships. By doing so, the subsurface will be
accurately placed according to the translated positions of its ancestor
surfaces.
