This was initially a PR to add kitdiff, but this now lives in it's own
crate: https://github.com/rerun-io/kitdiff
I needed to make the image loaders public, this way it's possible to
compose image loaders together (which allowed me to create a image diff
loader that uses two other image loaders). But you can't use the
`ctx.try_load_image` since that would deadlock, so you have to store a
reference to the other loader in the wrapping loader.
This adds a new `Plugin` trait and new `input_hook` and `output_hook`
plugin fns. Having a `Plugin` trait should make it easier to store state
in the plugin and improve discoverability of possible plugin hooks.
The old `on_begin_pass` and `on_end_pass` have been ported to use the
new plugin trait, should we deprecate them?

That PR changed the tooltip to preserve the wrapping, which made the
tooltip kind of useless. With this PR the wrapping is reset for the
tooltip.
This adds a new mode, `UPDATE_SNAPSHOTS=force`, which will lower the
threshold to zero, overwriting every image that is not _exactly_ the
same.
Most comparisons has a threshold because different GPUs render slightly
differently. However, setting that threshold accurately can be hard.
Sometimes a test will pass locally, but fail on CI. In those cases you
want to force an update of the failing test. You can use
`UPDATE_SNAPSHOTS=force` for that.
And sometimes a small change _should_ update all images, but the change
is so tiny that it falls under the threshold. Still, you want to make a
point of showing that these images have changes. You can use
`UPDATE_SNAPSHOTS=force` for that.

Currently, DatePickerButton will close without saving whenever a user
clicks a dropdown from year/month/date. The issue is caused because the
system mistakenly interprets the user as clicking off of the calendar.
This is unexpected and creates an unpleasant experience for the user.
This change now allows the user to use the dropdowns as expected; it
will close on save or cancel. The calendar still closes when user clicks
off of it, as before. The changes here are made in:
crates/egui_extras/src/datepicker/button.rs
I will admit that I am not an experienced Rust developer. The changes
were made with the help of ChatGPT 4.0.
I have tested the changes locally, as I am using the date picker in my
project.

This allows us to programatically move focus around. Another way would
be to inject arrow key inputs, but that requires the backend to
implement a way to do that, and could have unintended side-effects.

Removes the `deadlock_detection` feature, since we now have a more
primitive panic-after-30s deadlock detection which works well enough and
even detects kinds of deadlocks that the `deadlock_detection` feature
never supported.
Turns out the default timeout for github actions is 6 hours (!). This PR
sets some reasonable default for all workflows, the ones invoking cargo
in some way are limited to 60 minutes and the remaining ones to
10-15mins.
* 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.

Currently `ui.put` moves the cursor after the placed widget. In my
opinion that is a bit unexpected and counterproductive in most cases
where `ui.put` makes sense.
The following example breakes with the current behavior and looks right
with my change:
```rs
ui.horizontal(|ui| {
let custom_button_id = Id::new("custom_button");
let response = Button::new((
Atom::custom(custom_button_id, Vec2::splat(18.0)),
"Look at my mini button!",
))
.atom_ui(ui);
if let Some(rect) = response.rect(custom_button_id) {
ui.put(rect, Button::new("🔎").frame_when_inactive(false));
}
let custom_button_id = Id::new("custom_button");
let response = Button::new((
Atom::custom(custom_button_id, Vec2::splat(18.0)),
"Look at my mini button!",
))
.atom_ui(ui);
if let Some(rect) = response.rect(custom_button_id) {
ui.put(rect, Button::new("🔎").frame_when_inactive(false));
}
});
ui.add_space(10.0);
let response = ui.button("Notifications");
ui.put(
Rect::from_center_size(response.rect.right_top(), Vec2::splat(12.0)),
|ui: &mut Ui| {
Frame::new()
.fill(Color32::RED)
.corner_radius(10.0)
.show(ui, |ui| {
ui.label(RichText::new("11").size(8.0).color(Color32::WHITE));
}).response
},
);
ui.button("Some other button");
```

I had a look at reruns source code and there are no uses of `ui.put`
that would break with this change (very little usages in general).
## Alternatives
Instead of a breaking change we could of course instead introduce a new
metheod (e.g. `Ui::place`?).
