+
+    There is one shape factor for each point. The value of this factor
+    must be between -1 (which means that the spline is interpolated at
+    this point) and 1 (which means that the spline is approximated at
+    this point). The spline is always smooth in the neighbourhood of a
+    control point, except when the value of the factor is 0 for which
+    there is a first-order discontinuity (i.e. angular point).
