Proposal to add ROUTE VIEWER function to view track information of OPENBVE.

The current ROUTE VIEWER can view the curvature and layout of the route in 3D, but it is not intuitive to see the whole at a glance. Also, in the current ROUTE VIEWER, you cannot see the slope status.
We propose a new function for this.

Add a mode in the ROUTE  viewer.
When you press the hotkey (any), a new window will open and a separate window will open that performs the following functions.

1. Full Path Visualization (GRAPH)
Draw a straight line from start to finish.
Mark the block position by 25 (or block units).
2. If there is a curve, mark the start and end of the section and display the R value and C value.
3. If there is a GRADIENT, it is displayed in the corresponding section.
4. If there is a RAIL statement in the corresponding block position, LAYOUT is expressed with different colors for each RAIL index color.
At this time, the X value at each block position is displayed.

  You can drag side to side by activating the direction or scroll on the keyboard, and you need to zoom in and out.

If you enter the distance in ROUTE VIEWR, it will be linked and the display distance in this new window will also show the same.
Similarly, in ROUTE VIEWR, if you press 9 or 3 on the keypad to move the viewpoint back and forth, the new function window will move accordingly.

If desired, it should be possible to export the route status in PNG (image) or CSV, TXT (text) format.

If we add the features suggested above, we believe that route creators will be able to create routes more comfortably.

There's actually a semi-working initial prototype for something like this as part of this PR (although aimed at in-game map use):

The scale and speed of that are an issue though- Drawing the map is slow. Curves on secondary tracks are also an issue, as the current parser doesn't really allow for these properly.
If you think it'd be useful, I could probably get Route Viewer to export that into an oversized image?

The short answer is that a lot of this type of stuff is on the 'working on it' plate.
Unfortunately, most things are highly interdependant on one another.
