Random tileset terrain painting

[Reizoukodesu]

A friend of mine topaxi had the idea to paint cliffs randomly of the same type. I couldn't find any functionality or an issue to something similar, so I've created a prototype function:

https://github.com/Sapena/OpenRA/tree/similar_terrain_tilesets b86ea5a9d0a422c9da83da76a617939f88688155

The idea is to be able to drag a line of cliffs and the editor switches automatically the templates, but only using similar tiles. The prototype for now only works with the vertical and horizontal cliffs (Excluding the diagonal cliffs):

• Horizontal: 135-141, 149-155
• Vertical: 142-148, 156-162

The functionality could be applied to other kind of tiles, like water cliffs, roads, etc. Another extended and nice functionality would be, that the editor is able to handle displacements, like moving upwards while dragging a horizontal line.

Is this idea usable? Or just kind of overkill?

There is a cliff drawer in Final Alert 2 even i don't use that much. That would be good to have one in OpenRA's Editor.

Forgot to mention that the prototype is only roughly tested for the RA mod.

Here a little demonstration of the idea I tried to describe

I left a comment in #10655 about how we could implement this in a cross-mod compatible way.

Another good idea for map makers !

If we do this as its own brush type (as per #10655) I suggest that we render the preview as a 2x2 block of the white selection overlay to indicate that you're not placing any specific cliff type.

Good input, so it is easier to stay within the line and it is less confusing.
