[1.1.68] Unknown item sprite displays poorly in alt mode

[sparr]

The sprite for unknown-item is a black question mark. This looks fine in the GUI where it will be backed by a crisp grey square. It looks terrible in Alt mode where it will appear on top of an entity with a black gradient surrounding it. A white outline is one potential way to resolve this.

Thanks for the report however I don't believe we plan to ever do anything about this. The nature of that icon means is only ever intended to be shown in GUIs. The fact it *can* be set on an in-world entity through mods, scripts, or the map editor is not a concern. At best we would prevent doing that as a fix; but that seems unnecessary for now.
