Actually that was the plan (including a GetNormal callback for optional
pre-computed normals), but I just realised that with this interface the app
could indeed be working of splines if it wanted to, and an approximate
triangle would be constructed from it internally as you suggest.

So it's actually more flexible than I thought : ).
