Previously, when `rect` was taller than it was wide, the spinner would
render far outside the given rectangle. Now, it always renders inside
the smaller of the two dimensions.
I noticed this when upgrading from 0.30 to 0.32. I have an image that's
significantly taller than it is wide. In 0.32, when the image is
loading, it shows the spinner. Since the spinner radius is determined
solely based on rectangle height, the spinner ends up far too wide and
covers other elements.

This changes egui to create an AccessKit node for each `Ui`. I'm not
sure if this alone will directly improve accessibility, but it should
make it easier to create the correct parent / child relations (e.g.
grouping menus as children of menu buttons).
Instead of having a global stack of parent ids, they are now passed via
a parent_id field in `UiBuilder`.
If having all these `GenericContainer` nodes somehow is bad for
accessibility, the PR could also be changed to only create nodes if
there is actually some accessibility info with it (the relevant is
currently commented-out in the PR). But I think screen readers should
just ignore these nodes, so it should be fine? We could also use this as
motivation to git red of some unnecessary wrapped `Ui`s, e.g.
CentralPanel creates 3 Uis when 2 should be enough (the initial Ui and a
Frame, maybe we could even only show the `Frame` if we can give it an
UiBuilder and somehow show the Frame with `Ui::new`).
Here is a screenshot from the accessibility inspector
(https://github.com/emilk/egui/pull/7368) with this PR:

- I broke this in #7577
`pull_request` workflows don't have permission to comment, so we have to
do this via a `pull_request_target` workflow.
The point of this early comment is that the kitdiff link appears as soon
as possible and isn't dependent on the preview build suceeding.
Adds an accessibility inspector plugin that shows the current AccessKit
tree:
https://github.com/user-attachments/assets/78f4f221-1bd2-4ce4-adf5-fc3b00f5c16c
Macos has a built in accessibility inspector, but it doesn't seem to
work with AccessKit / eframe so this provides some insight into the
accesskit state.
This also showed a couple issues that are easy to fix:
- [ ] Links show up as `Label` instead of links
- [ ] Not all supported actions are advertised (e.g. scrolling)
- [ ] The resize handles in windows shouldn't be focusable
- [ ] Checkbox has no value
- [ ] Menus should have the button as parent widget (not 100% sure on
this one)
Currently the plugin lives in the demo app, but I think it should be
moved somewhere else. Maybe egui_extras?
This could also be relevant for #4650
Adds a helper to quickly see whats going on in a kittest test.
Not all test have snapshots, but when debugging tests it might still be
useful to see whats actually going on, so this adds a helper fn that
renders a snapshot image to a temporary file and opens it with the
default image viewer:

This PR is a continuation of #4915 by @frederik-uni and @lucasmerlin
that introduces support for keeping egui content within the 'safe area'
on iOS (avoiding the notch / dynamic island / menu bar etc.), with the
following changes:
- `SafeArea` now wraps `MarginF32` and has been renamed to
`SafeAreaInsets` to clarify its purpose.
- `InputState::screen_rect` is now marked as deprecated in favour of
either `viewport_rect` (which contains the entire screen), or
`content_rect` (which is the viewport rect with the safe area insets
removed).
- I added some comments to the safe area insets logic pointing out the
[safe area API coming in winit
v0.31](https://github.com/rust-windowing/winit/issues/3910).

* Closes https://github.com/rerun-io/rerun/issues/11301
This fixes a bug where a menu could get stuck, not closing at all, when
the currently open submenu stops being shown.
I also added a way to reproduce this to the demo, as well as a test
ensuring that there is no race condition in the fix.
This adds a new workflow `update_kittest_snapshots.yml` that can be
triggered through the [kitdiff](https://github.com/rerun-io/kitdiff) ui
when viewing a ci artefact.
Also adds a link to kitdiff to view the pr changes to each commit (via
the preview build comment)
