For the test I added a `Harness::press_key` function. We should
eventually add these to kittest, probably via a trait one can implement
for the `Harness` but for now this should do.
As someone who uses "grey" instead of "gray", it is annoying that my
autocomplete can never find any of the "gray" color related things, so
this adds doc aliases for that.

The allows us to pass any state to the ui closure. While it is possible
to just store state in the closure itself, accessing that state after
the harness was created to e.g. read or modify it would require interior
mutability. With this change there are new `Harness::new_state`,
`Harness::run_state`, ... methods that allow passing state on each run.
This builds on top of #5301, which should be merged first

This adds a `Harness::new_ui`, which accepts a Ui closure and shows the
ui in a central panel. One big benefit is that this allows us to add a
fit_contents method that can run the ui closure with a sizing pass and
resize the "screen" based on the content size.
I also used this to add a snapshot test for the rendering_test at
different scales.

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.
egui never accesses the `FontDefinitions`' member fields mutably, except
in `fonts_tweak_ui` where it cloned the `FontDefinitions` object anyway.
This patch reduces system memory consumption for shared font
definitions.
And also removes some overhead from copying (e.g. for the per
`pixel_per_points` font atlas)
Also it allows to keep a copy of the font definitions outside of egui.
In my App that uses international fonts:
Before:
New:
Note: If `Arc` is not wanted, then it could ofc be abstracted away.
I know this is quite a breaking change API wise, but would like to hear
your opinion.

The `RawInput::dropped_files` documentation referred to `NativeOptions`,
but the `drag_and_drop` option was moved to `ViewportBuilder` and is now
enabled by default.
Note that drag-and-drop is not *explicitly* enabled by default here, but
rather is enabled by default in winit. We only override winit's default
if the API consumer specifies it. It might be a good idea in general to
provide explicit defaults for everything in `ViewportBuilder` so we're
not relying on winit's behavior, but that's best left for another PR.

I am preparing a separate PR that adds support for JXL with `jxl-oxide`,
which is unlikely to be added to the `image` crate anytime soon (more
context will be provided in that PR).
`jxl-oxide` makes use of the
[`array::each_mut`](https://doc.rust-lang.org/stable/std/primitive.array.html#method.each_mut)
API which was stabilized in 1.77, which is the motivation for this MSRV
bump.
Rust 1.77 was officially released to stable on 21 March, 2024.
This adds `egui_kittest::try_image_snapshot_options` and
`egui_kittest::image_snapshot_options`, as well as
`Harness::wgpu_snapshot_options` and
`Harness::try_wgpu_snapshot_options`

When mixing and matching eframe with other wgpu applications
(https://github.com/tracel-ai/burn in my case), it can be helpful to use
an existing wgpu setup to initialize eframe with. This PR changes the
WpuConfiguration (in a non-backwards compat way :/), to either take some
options how to create a wgpu setup, or an existing wgpu setup
(consisting of an instance, adapter, device and queue).

Currently `Style::override_font_id` does not affect widgets with their
`TextStyle` like `Button`s, `ComboBox`es, `CheckBox`es, etc. This PR
fixes this behavior such that all widgets using default configuration of
`RichText` are affected by this setting.

Fix: Window::default_pos does not work
Issues: Since `default_size` is not applied to `area`,
`style.spacing.default_area_size` is applied, causing problems.
* Closes#5314
Exposed the underlying PopupCloseBehavior of ComboBox in order to allow
more control of ComboBox behavior.
This allows ComboBox to be used rather than manually managing a popup
directly, while also gaining the convenience features of ComboBox such
as popup auto-sizing.

`Box<str>` is an immutable heap-allocated string slice.
This PR makes it more convenient to use them in labels for example.
Before this PR
```rust
let text: Box<str> = "Hello".into();
ui.label(text.into_string());
let text_ref: &Box<str> = &"Hello".into();
ui.label(text_ref.clone().into_string());
// or
ui.label(text_ref.as_ref());
// or
ui.label(&**text_ref);
```
After this PR
```rust
let text: Box<str> = "Hello".into();
ui.label(text);
let text_ref: &Box<str> = &"Hello".into();
ui.label(text_ref);
```

Previously, all widgets would be listed in accesskit as children of the
toplevel window.
With this change, they will be reported as child of the `egui::Window`
they are in, Which should increase parseability of the ui for
screenreaders and integration tests.
Added an accesskit test to check that it is indeed working.

Since textedit is doing the justify layout calculation itself, we need
to report the original desired_size as intrinsic size, instead of the
value passed to allocate_space.
I wonder though, is it still necessary that the TextEdit does the
justify calculation itself instead of relying on the ui layout to do it?
As far as I understand it, justify should be handled by the
ui.allocate_space call.
The check.sh script was broken in #5166, this fixes it

winit::Window::inner_size returns size of safe area on iOS. use
winit::Window::outer_size on iOS
The dimensions of outer_size include the title bar and borders, but as
far as I know there is no way to actually display the title bar or
borders on iOS so it should be fine.

This shortcut was previously triggering the Undo action due to the
matches_logically method ignoring the state of the Shift key. This was
solved by simply inverting the order of the undo and redo arms, so the
undo is not matched if the shortcut corresponds to redo.

This should hopefully make it easier for egui contributors and
egui_kittest users to understand the snapshot tests
* [X] I have followed the instructions in the PR template
- closes#3491
- closes#3926
This adds a testing library to egui based on
[kittest](https://github.com/rerun-io/kittest). Kittest is a new
[AccessKit](https://github.com/AccessKit/accesskit/)-based testing
library. The api is inspired by the js
[testing-library](https://testing-library.com/) where the idea is also
to query the dom based on accessibility attributes.
We made kittest with egui in mind but it should work with any rust gui
framework with AccessKit support.
It currently has support for:
- running the egui app, frame by frame
- building the AccessKit tree
- ergonomic queries via kittest
- via e.g. get_by_name, get_by_role
- simulating events based on the accesskit node id
- creating arbitrary events based on Harness::input_mut
- rendering screenshots via wgpu
- snapshot tests with these screenshots
A simple test looks like this:
```rust
fn main() {
let mut checked = false;
let app = |ctx: &Context| {
CentralPanel::default().show(ctx, |ui| {
ui.checkbox(&mut checked, "Check me!");
});
};
let mut harness = Harness::builder().with_size(egui::Vec2::new(200.0, 100.0)).build(app);
let checkbox = harness.get_by_name("Check me!");
assert_eq!(checkbox.toggled(), Some(Toggled::False));
checkbox.click();
harness.run();
let checkbox = harness.get_by_name("Check me!");
assert_eq!(checkbox.toggled(), Some(Toggled::True));
// You can even render the ui and do image snapshot tests
#[cfg(all(feature = "wgpu", feature = "snapshot"))]
egui_kittest::image_snapshot(&egui_kittest::wgpu::TestRenderer::new().render(&harness), "readme_example");
}
```
~Since getting wgpu to run in ci is a hassle, I'm taking another shot at
creating a software renderer for egui (ideally without a huge dependency
like skia)~ (this didn't work as well as I hoped and it turns out in CI
you can just run tests on a mac runner which comes with a real GPU)
Here is a example of a failed snapshot test in ci, it will say which
snapshot failed and upload an artifact with the before / after and diff
images:
https://github.com/emilk/egui/actions/runs/11183049487/job/31090724606?pr=5166
* Closes#5224
I'm unfamiliar with wgpu, so I'd like someone to confirm, that calling
`wgpu::Texture` _after_ `wgpu::Queue::submit` is in fact the right thing
to do.
