-----------
DXF-exporter script update: v1.37 - 2010.06.23 by migius
- APPLY-MODIFIER: added exception for modifier-free instances to export them as
BLOCK/INSERTs
DXF-export library update: v1.35 - 2010.06.23 by migius
- added (as default) writing to DXF file without RAM-buffering: faster and
low-RAM-machines friendly
