Goober5000 e2707549f4 add documentation for issue 4148 ...

Per Claude:

The key things the new comments add that the old ones were missing:

1. Palette RGB colors are completely ignored — only the index value is used as alpha. This is the non-obvious invariant that @notimaginative described.
2. Exact mapping table — makes the * 18 / * 17 math immediately readable, and clarifies the ANI vs PCX difference (> 15 clamps to opaque in ANI but transparent in PCX).
3. The broken-palette consequence — explicitly states that a reversed palette causes a white square, linking to #4148 so future readers understand the context.
