add height and normal map conventions to U3M spec #32

I'd like to suggest adding the normal map and displacement map conventions to the specification:

  1. The normal map is using OpenGL convention (as opposed to DirectX convention used by some 3D graphics tools)
  2. The displacement map has higher values closer to the camera for an overhead view I believe this matches the way U3M files are being created and used.
