feat(editor): the top view of the tracks draws the terrain to the corners of the screen, the ballast optional

Browse Source 
- In the top view of the tracks work area, the renderer's reach is the half diagonal of the screen. It used to be three extents, which cut wide windows short.
- Cells far from the camera no longer draw only their tracks: the terrain shapes are drawn too. Models keep their own ranges.
- In that view, the heightmap streamer loads chunks as far as the corners, up to 50 km. The detail comes from the size of a pixel, not from the distance.
- The walk over the chunks around the camera is skipped while it would ask for nothing, so a wide reach costs little.
- A setting, kept in the editor settings, leaves out the ballast of the railway in the top view, so the ground under the tracks shows. It is in the View menu and next to the extent slider.
- Self-test: ortho <extent> [noballast|ballast], orthophoto off.
