+to do list
+
+* Separate arrows, possibility to add them to curves.
+
+* Conversion pt -> bp will omit the scale factor at the output. (multiplying
+the dimension by 0.99626401 before removing pt).
+
+* Add operator for rotation. (Otherwise graphics should be used.)
+
+*? Test slope coordinates to be real number (see below), not rounded to zero.
+Ths is pribably not necessary - too complicated, waste of computer time and
+with almost no interesting effect.
