+ * \file point3d.hxx
+ * A 3d point class (depricated).  This class is depricated and we are
+ * in the process of removing all usage of it in favor of plib's "sg"
+ * library of point, vector, and math routines.  Plib's sg lib is less
+ * object oriented, but integrates more seamlessly with opengl.
