With the new technique of figuring out how much part images can overlap each
other (tighter packing algorithm), PACK SUBS is not invoked, if there is
overlap.
Currently, the overlap detection process only has to check the the previous part
added to the column to find maximum overlap.
With PACK_SUBS, a new part added to the column has to check against all the
parts at the previous row, which could be many parts. LPub has never needed to
track the contents of the previous row before, so the data structures needed
don't currently exist.
I'll examine the code and stop discarding the BOM LDraw files.

I suspect this problem has been there for a while (maybe since the change to
LPub/LDraw, or further back). The file path looks all wrong.
