Angle strategy (alpha strategy)

The alpha strategy features the fact that it specifies the angle from which a linear segment is calculated when viewed in the reverse direction, starting from the current position of the down channel.

If the straight line intersects the Z axis below the escape point (radius 0), a perpendicular motion takes place from there to the escape point (bottom left figure).
If radius zero is not reached below the escape point, a horizontal motion takes place from the point of intersection with the horizontal to the escape point (bottom right figure)

If an angle of 90 degrees is specified, this corresponds to the behaviour of the Flat strategy.
