I don't see any flags there.

For what it's worth, this is now in the 3dfloors2 branch.

Maybe because I'm doing other stuff.

So why don't you do that, then?

I've been wanting to add a new color for 3D floor boundaries for a while now...

This sounds really damn useful, especially with 3D floors.

Similar to the Secret and Never Show flags, I would like to be able to flag lines as floor/ceiling differences. This has a few different uses:

- For 3D floors, one could simply flag the outer lines of the destination sector, rather than needing to make a 1 unit floor or ceiling difference in order to show things like bridges or tables on the map.
- It could be used to draw static arrows or other marks on the map, without needing make them dark like impassable lines.
- It could be used to mark the borders between different floors that are the same height, where usually the lines between would be invisible.

I imagine precedence would be:
1. Never Show
2. Secret
3. Floor Difference
4. Ceiling Difference

(For 3 and 4, I'm going by in-game behavior: Lines with both floor and ceiling height changes show the color for floor difference.)
