Include popups and tooltips in `Harness::fit_contents` (#7556)

Make individual egui_extras image loaders public (#7551)
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.

New Plugin trait (#7385)
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?

Reset wrapping in label tooltip (#7535)

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.

kittest: Add `UPDATE_SNAPSHOTS=force` (#7508)
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.

Fix: prevent calendar popup from closing on dropdown change (#7409)
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.

Remove the `deadlock_detection` feature (#7497)
* 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.

Fix deadlock in `ImageLoader`, `FileLoader`, `EhttpLoader` (#7494)
* 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.

Add `Ui::place`, to place widgets without changing the cursor (#7359)
* Closes <https://github.com/emilk/egui/issues/7353>

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
clicked due to ui being disabled.

Fix debug-panic in ScrollArea if contents fit without scrolling (#7440)
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.

Fix `override_text_color` priority (#7439)
The override_text_color is now used when rendering text from a String or
&str. This is consistent with the RichText variant and makes the option
behave as advertised, taking precedence over WidgetVisuals and
overriding the color for all text unless explicitly changed for a single
widget (via RichText or LayoutJob).

I'm running a rustup-less rust install on Windows, so I don't have

It's very little code and I manually tested this, so hopefully that's
ok...

Fix manual `Popup` not closing (#7383)
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):

Add `UiBuilder::global_scope` and `UiBuilder::id` (#7372)
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.

This feature can be used to fix a issue i am having with the

describes exactly how I encountered this issue:

> That assert is wrong if something calls forget between the start of

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.

Make the font atlas use a color image (#7298)
* [x] I have followed the instructions in the PR template

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.

`egui_kittest`: add `failed_pixel_count_threshold` (#7092)
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.
