* Recently CI runs started to hang randomly:
https://github.com/emilk/egui/actions/runs/17427449210/job/49477714447?pr=7359
This fixes the deadlock and adds the basic deadlock detection we also
added to Mutexes in #7468.
Also, interestingly, the more sophisticated deadlock detection (behind
the deadlock_detection feature) didn't catch this for some reason. I
wonder why it exists in the first place, when parking_lot also has built
in deadlock detection? It also seems to make tests slower, widget_tests
usually needs ~30s, with the deadlock detection removed its only ~12s.
This is the same issue that was fixed for the http bytes loader in
239ade9a59

Funnily, [this
comment](https://github.com/emilk/egui/issues/3747#issuecomment-1872192997)
describes exactly how I encountered this issue:
> That assert is wrong if something calls forget between the start of
the request and the end of it.
I'm displaying lots of images in a scrolling grid (20 or so visible at a
time). It seems like image textures are never freed up automatically so
it stacks up a lot meaning I have to unload the image textures manually
with `egui::Context::forget_image()` in each `eframe::App::update()`
call for the images that are no longer shown when scrolling.

With kittest it was difficult to wait for images to be loaded before
taking a snapshot test.
This PR adds `Harness::with_wait_for_pending_images` (true by default)
which will cause `Harness::run` to sleep until all images are loaded (or
`HarnessBuilder::with_max_steps` is exceeded).
It also adds a new ImageLoader::has_pending and
BytesLoader::has_pending, which should be implemented if things are
loaded / decoded asynchronously.
It reverts https://github.com/emilk/egui/pull/6901 which was my previous
attempt to fix this (but this didn't work since only the tested crate is
compiled with cfg(test) and not it's dependencies)
https://github.com/emilk/egui/pull/5394 made it so images would load on
a background thread, which is great. But this makes snapshot tests that
have images via include_image!() flakey since they might or might not
load by the time the snapshot is rendered.
This is no perfect solution, since the underlying problem of "waiting
for something async to happen" still exists and we should add some more
general solution for that.
This is the same change as in #4069 but as this is stale I wanted to
reopen a non stale PR
Modifies ImageLoader's load function to use background threads for the
image decoding work. This avoids blocking the main thread that is
especially noticeable when loading many images at once.
This was modelled after the other loader implementations that also use
threads.

Hi !
I'm using egui and egui_extra to build a demo tool for a crate I'm
building. In this crate I load favicons from a lot of websites, and I
have some failures on some .ico files. After tracking this thing down, I
guess there is two issues (kinda), in the image crate,
'image/vnd.microsoft.icon' isn't recognized as the valid mime for an ico
image (I created a [PR](https://github.com/image-rs/image/pull/2434)),
and the code to detect if a given mime type is compatible with the image
crate decoders in this crate do not support multi-mime type formats.
[ImageFormat::to_mime_type](85f2412d55/src/image.rs (L216C12-L216C24))
is only returning one mime for a given format (which is fine), we
compare the result of this method to guess if the format is
valid/enabled. Retriveing the correct format using
[ImageFormat::from_mime_type](85f2412d55/src/image.rs (L166))
would allow more mime to be considered valid since multiple mime can
match the same format.
The same applies to the extension detection, which I also modified to
stay consistent
Thanks
Hi, after upgrading to 0.31.0 all of my beautiful static webp images
started failing to load. I use the image_loader to load those via the
`image` crate.
I noticed that with 0.31.0 there are additions to how animated image
types are handled with frames and such. And with those changes the frame
index is attached to the uri at the end. This was problematic for the
image_loader, because it wasn't updated to handle that frame tag at the
end of the uri, so when looking up the bytes, it would fail to match the
uri in the bytes cache (the bytes were being saved without the frame
index, but attempting to be fetched _with_ the frame index).
This fixes the image_loader for me with webp & gif. They don't load the
animations, but I think that is because I don't have the custom
image_loader set up so I'm not worried about that for myself. I'm not
sure if that part is problematic in general, or if its just the way I
have my features set up.
You can recreate the issue on master by swapping out the dependency
features in the `images` example like this:
```
# egui_extras = { workspace = true, features = ["default", "all_loaders"] }
# env_logger = { version = "0.10", default-features = false, features = [
# "auto-color",
# "humantime",
# ] }
# image = { workspace = true, features = ["jpeg", "png"] }
egui_extras = { workspace = true, features = ["image", "svg"] }
env_logger = { version = "0.10", default-features = false, features = [
"auto-color",
"humantime",
] }
image = { workspace = true, features = ["jpeg", "png", "webp", "gif"] }
```

I removed the webp supported URI test given that the webp feature would
have to be enabled. I kept that webp is not supported in the other
tests.
There might need to be an additional warning in the changelog that image
support detection is now stricter.

Not sure what the "best practice" is, to me it seems like one should
import from "the original location" if possible, but now it should at
least be possible to not re-export ahash without any breakage in the
egui code base (but possibly in projects using egui, so one should
probably deprecate it if one would like to go that path). It also seems
like epaint re-exports ahash.
