Request formation Rank state images

I am adding functionality to the custom line widget to have units

Here is a game where I used it: https://zero-k.info/Battles/Detail/1288908

I will need 4 image for these. Please use existing sizes/colors from existing states found at: https://github.com/ZeroK-RTS/Zero-K/blob/master/LuaUI/Images/commands/states/

I want something like:

For rank 0 (front rank):
----0----
---------
---------
---------

For rank 1 (middle-front rank):
---------
----0----
---------
---------

For rank 2 (middle-back rank):
---------
---------
----0----
---------

For rank 3 (back rank):
---------
---------
---------
----0----

But you can use your art skill to make it look better. Probably don't want it too fancy.

The main issues left with line formation are testing, artwork, excluding all planes other than crane, and excluding units that are under construction.

My original thought did not have the '0's, so the 2nd color was to show what line the unit was on. With the '0's on the line (implying that the '0' is the unit on that line), the images could be single color. I think I like the line to be a second color to draw attention to that line, but I'll leave it up to the artist. Getting GoogleFrog approval may be another issue that I will also leave up the artist. The selected line could also be thicker than the rest. I am not sure if I like the line to have a different thickness, but maybe if I saw it.
