feat(track): at a crossing at a wide angle the tread of the other track is laid where its wheels roll over the mitred corners: the part of a guard rail under the running rail of the other track becomes a running surface in the shared tread material instead of matte, and running rails of different materials share the tread over the rolled band of the other track instead of over a square span; wide_tread draws the edges of the band from the crossing itself, since the gauge lines meet in one point at right angles, and a tread gives its own fade, widened for bands lying across the rail; treaded keeps the matte parts of a guard rail matte, lay_treads splits guard rails at their treads, and a piece of no triangles is not inserted
