Help understand interactions with lua/ui/game/rangeoverlayparams.lua

[Garanas]

The parameters that you can provide through Lua are reasonably self-explanatory, but how does the engine determine the radius value? And would it be possible to introduce new range rings?

As a few examples:

• Possibility for separate shield, TMD and SMD rings
• Possibility for separate tactical missiles, strategical missiles and artillery rings
