Hi, one more request for mod support. Basically, to support this more readily I'd like to be able to tint/layer existing icons for some items.

Could your mod accept an optional "icons" parameter in HotMetals.items table entries? Then if item.icons is present, you can assign it to the hotItem.icons instead of assigning hotItem.icon. Then modders could supply table entries sorta like this

{
  name="tin-plate",
  spoilTicks=10*60, 
  icons={
    { icon = "__bztin__/graphics/icons/tin-plate.png", icon_size = 128},
    { icon = "__bztin__/graphics/icons/tin-plate.png", icon_size = 128, tint={.9,.2,0, .5}},
  },
}

Let me know if I didn't explain my request clearly :)

Done with the next release.

Thanks for this as well!
