ceade 708cca9627 Changes to handling BFC

There are two major changes here:

1) Previously I was inverting the winding of verticies only when calculating the normal. This was the wrong approach and I instead needed to invert the order of the verticies before calculating the normal. This is because most STL processing software (eg: Slic3r) will recalculate the normals based off the winding (correctly).

2) I *think* I am doing proper BFC handling now, although TBH the BFC handling logic in ldraw is super complex to me. See: https://www.ldraw.org/article/415 ("Rendering Engine Guidelines").

ldraw2stl

Convert LEGO LDraw files to STL, for super-sizing and 3d printing!!

Get the ldraw parts archive at :

wget http://www.ldraw.org/library/updates/complete.zip unzip complete.zip bin/dat2stl --file ldraw/parts/3894.dat --ldrawdir ./ldraw
Install LeoCAD so you can find your parts (optional)
Make a note of the .dat file name in LeoCAD, and then run:

bin/dat2stl --file /usr/share/ldraw/parts/3894.dat --ldrawdir ./ldraw --scale 4 > 3894.stl

For a 4X scale one of those!
