Here's my review of PR #1294 — feat: WEBP support

Summary

Two commits (feat: WEBP support + WIP: more fixes) adding WebP image support (both static and animated) to notedeck. It adds the webp crate, creates a new WebpTexCache / WebpState system mirroring the existing GIF infrastructure, and routes image/webp MIME types to the new cache.

---

Critical Bugs

1. Job results delivered to the wrong cache

This is the showstopper. When a WebP job completes, fromdiskjobrun and fromnetrun return MediaJobResult::StaticImg(...) or MediaJobResult::Animation(...). But delivercompletedmediajob routes those into texcache.staticimage and texcache.animated respectively — not texcache.webp.

Meanwhile, runmediajobpreaction correctly marks the entry as Pending in texcache.webp, and all lookups go through texcache.webp. So the webp cache entry stays Pending forever and the actual texture is orphaned in the wrong cache.

WebP images will never render.

The fix is either:

Add a MediaJobResult::Webp(...) variant and handle it in delivercompletedmedia_job to insert into the webp cache, or
Use MediaJobResult::StaticImg/Animation but key the delivery off MediaJobKind::WebpImg to route to the right cache.

2. Static webp disk cache format mismatch

In the network path for static webp (fromnetrun), after decoding and processing, the image is saved via MediaCache::write(&path, &url, image) which writes PNG data. But when loading from disk (fromdiskjobrun), it reads the file and calls detectwebptype + decodestatic_webp — which expect raw WebP bytes. This will fail on the second load.

Either save the original webp bytes to disk, or use image crate decoding (which handles PNG) when loading from disk.

---

Design Concerns

3. Heavy duplication with GIF infrastructure

WebpState is field-for-field identical to GifState. processwebpframe is a near-exact copy of processgifframe. NoLoadingLatestTex now takes both caches + state maps as separate params and handles them with duplicated match arms. This should be unified — the animation state machine is format-agnostic.

4. Redundant webp crate for static images

The workspace already has image = { version = "0.25", features = ["jpeg", "png", "webp"] } — the image crate can decode static WebP. The separate webp crate is needed for animated WebP (which image doesn't support), but for static WebP, two decoders are redundant.

5. Re-encoding animated frames for disk cache

write_webp re-encodes individual frames back into a new animated WebP for disk caching. This is lossy round-tripping. It would be simpler and more correct to just save the original response bytes.

---

Minor Issues

writewebp: the referenceframe / data.first() check is redundant since data.is_empty() is already checked above
decodestaticwebpprocessed: unused ctx and _url parameters
The delay.into() call in generatewebpanim_pkg is an identity conversion (Duration -> Duration)
Commit message says "WIP" — should be cleaned up before merge

---

Verdict

The approach is reasonable (follow the existing GIF pattern for WebP), but the two critical bugs mean WebP images won't actually display. The job delivery routing needs to be fixed, and the disk cache format mismatch needs to be resolved. I'd also strongly suggest unifying GifState/WebpState and the frame processing logic to avoid the maintenance burden of two identical animation state machines.
