It doesn't help the minifig heads at all though, the problems on them (imho) isn't unique positional related. [/code]
That doesn't surprise me. The error I mention would only occur as TOL fraction of all times. Which is pretty small.

This whole thing could also be fixed by using the center axle of the minifig head to project a normal to any point on the face. But the renderer has no way of knowing this without ether hints in the LDraw files or hard coding this information for certain part families (e.g. 3626bp*)
Or in my dream world, by having a decent class of primitives for minifig heads.
