The problem appears to be with 'ssgTransform' nodes (transformation matrices embedded in the
scene graph).

Our loader *is* creating ssgTransform's at the appropriate points - but the numbers
in those matrices don't seem to be the ones you need.  As others have pointed
out, it doesn't appear as if that's our fault.  Clearly the coordinates of the
handle of the sword are rotated through 90 degrees - but there are no rotation
nodes in the DXF file.

If there is a way to tell Blender to 'flatten' the heirarchy (multiplying out the
matrices to that all the model's vertices are in the same frame of reference) - then
perhaps you'd be able to work around it's problems.

One problem that *is* a fault with our DXF reader is that when it reads the name
of a node, it includes the line-feed from the file in the name it passes to
SSG.  Hence, instead of the name field being 'CUBE', it comes out as 'CUBE^J'
in PPE.
