MODEL is relatively easy to crack but since they use a bit different
coordinate system and their part have different rotation/center points,
the conversion between LXF <-> LDR would be a pain which would need a
compatibility layer library with all the fixup data.
CHUNK, the part definition, seems a bit harder, but basically looks like
series of points and triangles.
Funny is that LEGO itself is using different format for their own
internal purposes - Wavefront/Maya .obj format (I don't know if they use
it for the actual part mold design or just for visualization purposes).
