feat(editor): the drawn tracks kept in the scenery as //$h lines as they are drawn: laying, pulling out of a free end, joining two ends and the parallel track record the whole line they belong to, its straights, arcs and transition curves, with the radii from the chord and the turn of the arcs and the transitions from the turn they make, in the same undo step; the curves read in the route window and the Curve tab are what the paths are, no transitions or cant made up for them; a curve ends at the point of reverse; a parallel arc is concentric with its source; the paths laid in pieces of up to 90 degrees match the kept design within their own approximation; 'Keep the line as it lies' for lines drawn before; self-test commands digitize and parallel; Polish translation
