Function Direction1(node1, node2, node3: integer): integer;
Returns the turning angle (0-359) at node2 when moving from node1 to node3 via node2. This is based on the coordinates of the nodes and doesn't take the actual polyline-layout into consideration.
Straight on is 0, to the left is 90, backward is 180 and to the right is 270.
