That explains everything!

Wow I have been fighting against perfly (partially) and didn't even know it.

So if I just make a call to
   pfdBldrMode(PFDGBLDR_AUTO_ORIENT, PFDGBLDR_ORIENT_PRESERVE);
                  or
   pfdBldrMode(PFDGBLDR_AUTO_ORIENT, PFDGBLDR_ORIENT_NORMALS);
(or use perfly -O 13,x) this should affect the pfdGeoBuilder state
appropriately before I load my model with pfdLoadFile, right?
