feat(editor): the work of the editor sessions not committed yet, as it stands: a curve traced on from the end of the diverging track of a switch goes on at its radius with no transition in, or from a straight right at the switch (alignment start_held, fit_going_on), the plan taking an end adjoining R 10 km or more for a straight; the switches and slips laid into curves, slid along them and laid alone on one straight (frame_path, switch slide); the route plan reading curves going on from the tracks adjoining, the kept designs taken or forgotten; the orthophoto and terrain model settings, downloads and layers, the tracks onto the terrain; the curvature of a path in the plan (bezier::plan_curvature); the Polish texts of all of it. Not built as committed
