Dt3dPoint represents points in 3-space.
This class has no virtual functions, in order to minimize its run-time size. (A terrain database can have millions of Dt3dPoints, so the vtable ptr can matter). i.e. Subclasses should not have any member data.
Several functions are provided to support backwards compatibility. Unfortunately, they do so at the expense of type safety. To disable these functions set the compile flag POINT_VERTEX_TYPESAFETY to 1.
