 +==Orthographic Projection and Z Depth Testing==
 +This is an incredibly useful feature. Don't waste the 3rd dimension just because you world is flat!
 +An orthographic projection means that objects are the same size regardless of how far away they are. e.g. no matter what '​z'​ is x and y are NEVER scaled.
 +However, '​z'​ is still passed through to the z-buffer this you can use it for hidden surface removal and the like.
