Lua Scripted Menu
Only a scripted menu is a good menu.
The following Lua code generates the result you're seeing on the screenshot.

No big deal but it shows how things will work. You will be able to script the in-game interface in the very same way.
Note (for people who are used to CS2D/Carnage Contest Lua scripting): The color commands have 4 parameters. The last one is the alpha value. The parameters range from 0 to 1 (not from 0 to 255).
The used images in this shot are obviously NOT final but only placeholders!

Scaling
Moreover I decided to allow scaling objects in the editor. It's already fully implemented. You can either scale proportionally (change scale in all directions in the same magnitude) or you can change the scale on single angles for example to get a palm tree which is just very high.
