//! Regression: a BLP2 texture with an unknown `alpha_type` byte must still decode. Real 1.12-era
|
|
//! particle/effect art (e.g. `particles/dust1.blp` — palettized, `alpha_bits == 0`, but a stale
|
|
//! `alpha_type == 2`) used to abort the whole decode in `wow_blp`; our fork falls back to no-alpha.
|
|
//! Skips (passes) when the client isn't present at `<repo>/WoW/Data`.
