The asset_extract tool now optionally writes wowee open-format
copies next to each extracted proprietary file:
--emit-png foo.blp → foo.png
--emit-json-dbc foo.dbc → foo.json
--emit-open shortcut for both
Originals are left untouched, so private servers (AzerothCore,
TrinityCore) that load from the manifest's .blp/.dbc paths
continue to work unchanged. The wowee runtime / editor can now
consume the open formats directly without an extra conversion pass.
Implementation:
- New tools/asset_extract/open_format_emitter.{hpp,cpp} encapsulates
the post-extract walk + per-file conversion.
- BLP→PNG uses BLPLoader::load + stbi_write_png with the same
dimension/buffer-size sanity guards the editor's texture exporter
applies.
- DBC→JSON mirrors the editor's DBCExporter::exportAsJson schema
(string/float/uint heuristic) so the runtime DBC overlay loader
can consume the output drop-in.
