plotter: We we trying to export mm but chose in 

Note that the comment in line 142 where the scale factor was set had the
correct value to indicate metric (1) but in the actual boilerplate, we
set imperial (0).  This has been around for 6-8 years, so it would seem
DXF is not our most popular export.

Note, I initially tried to use '1' to specify metric units but this was
not handled by DXF readers (QCAM, Inkscape).  Instead, scaling the page
units to inches properly seems to work.
