Since he was refering to HPGL images, I ASSUMED that they had originaly
been destined for a pen plotter or a device such as a milling machine.

How you hold the result, i.e. a plot or an circuit board, or a gear, etc,
is almost irrelevant. The plots themselves have an origin (0,0) and go from
there. 

However they may have an intended viewing direction, but AFIK that is
not in the HPGL file at all. (it is in tiff)
