+The difference between "by parameter" and "by length" modes becomes
+apparent on the edges with irregular parametrization (for example,
+b-splines which usually have irregular density by the length).
+For example, value 0.5 "by length" on such edge will produce the point
+in the middle of this edge (equidistant from both its ends); the same
+0.5 value "by parameter" will result in the point situated closer to
+one of the ends (depending on the actual parametrization).
