//               value returned by get_coord(), which will be either a

//               occasional times when it is necessary to get the
//               actual location in space of the vertex position (for
//               instance, to subdivide a concave polygon).
//
//               This function returns the actual coordinate value.
//               For a nonindexed vertex, its return value is the same
//               as get_coord(); for an indexed vertex, it looks up
//               the vertex's index in the bucket's coord array, and
//               returns that value.
//
//               Note that this makes some perhaps unwarranted
//               assumptions about indexed geometry; specifically,
//               that its value is valid at creation time, and that it
//               won't change too drastically during runtime.
