Add vehicle direction indicator in tiles mode.

Fixes #13269

Yay. o3o

EDIT: And just to make sure, what will the tile ID for it be? I'm guessing it's "cursor" from the look of it.

[BevapDin]

@chaosvolt Yes, that's it.

@kevingranade Any reasons why the logic to check for options and valid vehicle is duplicated? It could go into get_veh_dir_indicator_location, it could return tripoint_min or g->u.pos() when no pointer should be drawn.

[drbig]

I concur with BevapDin on having the logic checks in one place only.

[chaosvolt]

Curses, merge conflicts.

[kevingranade]

Yea that's superior, will do.

[kevingranade]

@chaosvolt That was one question I had, as a tileset author would you rather it be the same as the look around and aming cursor, or different?

[chaosvolt]

Sprite-wise I could just use the look/aim cursor, or add a separate sprite that's the same in a different color.

I'm guessing that getting the game to cite the tile_config entity for aim/look would be easier? That seems fine, yes.

[kevingranade]

Implemented @BevapDin's suggestion, and leaving it using "cursor" for now.

[chaosvolt]

That should work quite well, yes. For me at least, hopefully other active tileset authors are fine with it that way.

However it works out, at least it'll be well-timed if that changes, since I'm steadily working on another tileset update. I should probably be a bit more quick about it though, since accounting for a terrain item I added recently is on my to-do list. XP
