To remove an overlay on an object, you specify the actual icon name you wish to remove. What do you do if you have overlayed an icon_state of one object onto another object and you wish to remove it? How do you reference it, especially if you don't have a pointer to the particular object you copied from (i.e. it has been deleted).

For this case it's best to create a simple registry of objects, each representing a specific icon/state combination. Then you can just use Registry.AddOverlay('snake.dmi', "rattler") and Registry.GetOverlay('snake.dmi', "rattler").

I have some sample code at home--if you need it, I can post it tonight.

That's a good idea. I've actually coded myself something that works for my purposes, but I still think we should be able to remove an icon_state overlay by name. :-)
