Transparency is probably not what you want. If a trans. green poly is
in front of or on a red poly, the result is yellow.
What you want is OrderGroups. In polygon modeling, this is often
referered to as "sub-faces", polys that are rendered in an order that
guarantees one in front of the other without Z-fighting. Check the API
for OrderGroups.
