Non-Convex Faces Not Triangulated Correctly

[maxattack]

The triangulate() helper function in ofbx.cpp doesn't properly ear-cut non-convex faces, leading to non-internal edges being placed.

The algorithm is not too tricky -- it's called "ear-cutting." A reference: http://www-cgrl.cs.mcgill.ca/~godfried/teaching/cg-projects/97/Ian/algorithm1.html

Implementation was only ~200LOC

Hi, I'm not sure when will I get to this, but if you need this soon you can disable ofbx triangulation and and do correct triangulation on your side.

Yeah, that's what I've already implemented. Just putting it on your radar :)
