[Papervision3D] Correct Z-Ordering?

[echeese]

Well, subdividing my mesh doesn't seem like the best idea, meshSort may help,
but I think the best solution would be to switch to Away3D, but even that
doesn't offer the nice RectangleTriangleCuller I've come to love. I can't
decide what graphical glitch I'd rather have in my app: incorrectly sorted
triangles or missing triangles. sigh.
