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.

* related #7494
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.
* 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`?).

Adds a check for `ui.is_enabled()` when displaying the SubMenu items.
There were a few places the condition could be placed, but I figured
there was simplest. The inner button will already not be able to be

On touch devices you don't want the keyboard to disappear when
scrolling, so this PR adds a `SurrenderFocusOn` enum to configure on
what interaction to surrender focus.
I'm trying to debug a suspected deadlock in the CI for
https://github.com/emilk/egui/pull/7467
Since we use our own mutex wrappers, we can just panic if the lock is
too slow. Ugly and effective :)
If the ScrollArea's contents are smaller than the inner rect, but the
scrollbar is set to always visible, clicking on it led to a remap from
an empty range to calculate the new offset, which triggered a debug
assertion in the remap function, because the result is indeterminate.
Since in this case there is no need to scroll, we just skip the remap
and set the offset to 0 directly.

Fixes manually created popups (via `Popup::new`) not closing, since
widget_clicked_elsewhere was always false.
This example would never close:
```rs
let mut open = true;
eframe::run_simple_native("My egui App", options, move |ctx, _frame| {
egui::CentralPanel::default().show(ctx, |ui| {
let response = egui::Popup::new(
Id::new("popup"),
ctx.clone(),
PopupAnchor::Position(Pos2::new(10.0, 10.0)),
LayerId::new(Order::Foreground, Id::new("popup")),
)
.open(open)
.show(|ui| {
ui.label("This is a popup!");
ui.label("You can put anything in here.");
});
if let Some(response) = response {
if response.response.should_close() {
open = false;
}
}
});
})
```
I also noticed that the Color submenu in the popups example had a double
arrow (must have been broken in the atoms PR):

I added a new flag to the UiBuilder so that it is possible to move child
widgets around the ui tree without losing state information.
Currently there is no way to create child widgets with the same id at
different locations in the ui tree since ids change in relation the the
parent id. With the new flag a unique global scope can be created which
always results in the same ids even at different locations.
You still need to ensure that the widgets only get rendered once in
frame.

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.

This deprecates all popup-related function in `Memory`, replacing them
with the new `egui::Popup`.
The new API is nicer in all ways, so we should encourage people to use
it.
Previously a single-negative rectangle (where `min.x > max.x` XOR `min.y
> max.y`) would return a negative area, while a doubly-negative
rectangle (`min.x > max.x` AND `min.y > max.y`) would return a positive
area. Now both return zero instead.
There was a bug in how we decide where to place a `Tooltip` (or other
`Popup`), which could lead to tooltips jumping around every frame,
especially if it changed size slightly.
The new code is simpler and bug-free.

Splitting this out from the Parley work as requested. This removes
`FontImage` and makes the font atlas use a `ColorImage`. It converts
alpha to coverage at glyph-drawing time, not at delta-upload time.
This doesn't do much now, but will allow for color emoji rendering once
we start using Parley.
I've changed things around so that we pass in `text_alpha_to_coverage`
to the `Fonts` the same way we do with `pixels_per_point` and
`max_texture_side`, reusing the existing code to check if the setting
differs and recreating the font atlas if so. I'm not quite sure why this
wasn't done in the first place.
I've left `ImageData` as an enum for now, in case we want to add support
for more texture pixel formats in the future (which I personally think
would be worthwhile). If you'd like, I can just remove that enum
entirely.
* part of https://github.com/emilk/egui/issues/7264
* removes SelectableLabel (Use `Button::selectable` instead)
* updates `Ui::selectable_value/label` with IntoAtoms support
Had to make some changes to `Button` since the SelecatbleLabel had no
frame unless selected.
I thought about this - so we have two options here:
1. adding it to `SnapshotOptions`
2. adding it to every function which I do not like as this would be a
huge breaking change
## Summary
This pull request introduces a new feature to the `SnapshotOptions`
struct in the `egui_kittest` crate, allowing users to specify a
permissible percentage of pixel differences (`diff_percentage`) before a
snapshot comparison is considered a failure. This feature provides more
flexibility in handling minor visual discrepancies during snapshot
testing.
### Additions to `SnapshotOptions`:
* Added a new field `diff_percentage` of type `Option<f64>` to the
`SnapshotOptions` struct. This field allows users to define a tolerance
for pixel differences, with a default value of `None` (interpreted as 0%
tolerance).
* Updated the `Default` implementation of `SnapshotOptions` to
initialize `diff_percentage` to `None`.
### Integration into snapshot comparison logic:
* Updated the `try_image_snapshot_options` function to handle the new
`diff_percentage` field. If a `diff_percentage` is specified, the
function calculates the percentage of differing pixels and allows the
snapshot to pass if the difference is within the specified tolerance.

This is a really small PR so I am skipping the issue (based on
contributing.md). This change adds an optional field and thus non
breaking for the API.
I ran into an issue during my development of an alerts manager widget
([see PR](https://github.com/blackberryfloat/egui_widget_ext/pull/2))
where I needed a scrollable overlay that did not block clicking areas of
a parent widget when my alerts did not take up the entire parent. To
achieve this I detect the sizing pass via the invisible flag and only
render the alerts content and then on the next pass I add the scroll bar
in around the alert content. Whenever the alert content changed though I
would need to create a new Area with a new id to get proper sizing. That
is a memory leak so I wanted to reset the size state to trigger a sizing
pass. Memory is rightfully protected enough that the path to remove
memory was dropped and I just added a hook to set a resize flag.
I am sure there are better ways but this is what made sense to me.
Looking forward to thoughts.
~~Logistics wise, I have proposed it as a patch because I was based off
0.31.1 for testing. I was also thinking it could be released quickly. I
am happy to cherry pick onto main after. If that is not allowed I can
rebase to main and pull against that.~~ (rebased on main)

I need to scroll in a snapshot test in my app, and kittest had no

helpers to scroll to a node / scroll the scroll area surrounding a node.
The accesskit code says down/up/left/right `Scrolls by approximately one
screen in a specific direction.`. Unfortunately it's difficult to get
the size of a "screen" (I guess that would be the size of the containing
scroll area)where I implemented the scrolling, so for now I've hardcoded
it to 100px. I think scrolling a fixed amount is still better than not
scrolling at all.

I don't think this will make a difference in practice, but technically
there are three preference states:
* `dark`
* `light`
* `no-preference`
Previously we would only check for `dark`, and if not set would assume
`light`.
Not we also check `light` and if we're neither `dark` or `light` we
assume nothing.
