Not the bounding box: EPS files can have a non-zero origin (although it is not very useful). The header and the lack of the orientation comment are the key: the latter is somewhat ambiguously defined, and version 6.0 ghostscript started rotating figures to have height > width if it were included. -- Brian D.
