- replace switch fn with closures in some places.
- integrate the switch fn inside the main switch.
- make sure lifetime are defined for PanelSizer.
- remove some `mut`, `&`, and `*` where they superfluous.
- wrongly called `ctx()` when it was a variable 🤦.
- cannot use `impl Trait` in a variable declaration type.
following those steps:
1. Rename `egui::TopBottomPanel` with `egui::Panel`.
2. Rename `height` with `size` in all chained methods.
- `default_height()` to `default_size()`
- `min_height()` to `min_size()`
- `max_height()` to `max_size()`
- `height_range()` to `size_range()`
- `exact_height()` to `exact_size()`
if using `Panel::new()`, replace
- `TopBottomSide::Top` with `Side::Horizontal(HorizontalSide::Top)`
- `TopBottomSide::Bottom` with `Side::Horizontal(HorizontalSide::Bottom)`

This is a breaking change, requiring users to think about wether the
stroke is inside/centered/outside the rect.
When in doubt, add `egui::StrokeKind::Inside` to the function call.
Adds `RectShape::stroke_kind` so you can select if the stroke goes
inside, outside, or is centered on the rectangle.
Also adds `RectShape::round_to_pixels` so you can override
`TessellationOptions::round_rects_to_pixels`.
This is similar to `ScrollArea`, but:
* Supports zooming
* Has no scroll bars
* Has no limits on the scrolling
## TODO
* [x] Automatic sizing of `Scene`s outer bounds
* [x] Fix text selection in scenes
* [x] Implement `fit_rect`
* [x] Document / improve API

This pull request fixes a subset of #5492 by saving the application
state when the `suspended` event is received on Android. This way, even
if the user exits the app and closes it manually right after changing
some state, it will be saved since `suspended` gets fired when the app
is exited. It does not fix the `on_exit` function not being fired - this
seems to be a winit bug (the `exiting` function in the winit application
handler trait is not called on exit). Once it gets fixed, it may be
possible to remove logic introduced by this PR (however, I am not sure
how it would handle the app being killed by the system when in the
background, that would have to be tested).
I've tested the logic by:
* Leaving from the app to the home screen, then killing it from the
"recent apps" menu
* Leaving from the app to the "recent apps" menu and killing it
* Restarting the device while the app was running
In all of these instances, the state was saved (the last one being a
pleasant surprise). It was tested on the repository mentioned in #5492
with my forked repository as the source for eframe (I unfortunately am
not able to test it in a larger project of mine due to dependence on
"3rd party" egui libraries (like egui_notify) which do not compile along
with the master branch of eframe (different versions of egui), but I
believe it should work in the same manner in all scenarios). Tests were
conducted on a Galaxy Tab S8 running Android 14, One UI 6.1.1.
CI passed on my fork.

On Chromium and Firefox we get one annoying frame with the wrong size,
which can mess up the layout of egui apps, but this PR is still a huge
improvement, and I don't want to spend more time on this right now.

## Changes
- Use Python 3 in `scripts/lint.py`.
## Why
Some modern OS and distributions do not provide Python 2 by default.
This includes recent macOS versions.
I see that `scripts/generate_changelog.py` already uses Python 3, so I
don't think this change should be controversial.
Without this change, I am unable to run `./scripts/check.sh` on macOS
15.2 without installing Python 2 or adding alias for `python`
executable.

The next version of the `objc2` framework crates will have a bunch of
default features enabled, see
https://github.com/madsmtm/objc2/issues/627, so this PR pre-emptively
disables them, so that your compile times down blow up once you upgrade
to the next version (which is yet to be released, but will be soon).

`egui:🆔:IdSet` and `egui:🆔:IdMap` were already optimized to not do
additional hashing (because the `Id` already is a hash), but now they
are just type aliases for `nohash_hasher::IntSet/IntMap`.

[Area::compare_order()](ee4ab08c8a/crates/egui/src/memory/mod.rs (L1174-L1183))
is not a total ordering. If three layers A, B, and C have the same
`order` field but only A and B are present in `order_map`, then `A==C`
and `B==C` but `A!=C`. This can cause a panic in the stdlib sort
function, and does in [my
app](https://github.com/HactarCE/Hyperspeedcube/tree/v2.0) although it's
very difficult to reproduce.

Current WebP loader assumes all WebP images to be RGBA, which is the
case if the image is animated (that's what `image` crate assumes at
least). Static images can instead choose to exclude its alpha channel,
though it seems to be more of a default choice to include it, even if
it's not being utilized. Currently, loading a static RGB WebP image will
cause a panic when `ColorImage::from_rgba_unmultiplied` gets called in
the loader
```
thread 'main' panicked at /home/aely/.cargo/git/checkouts/egui-226fc7cdd51201c1/f87219d/crates/epaint/src/image.rs:97:9:
assertion `left == right` failed
left: 29184
right: 21888
```
Previously, `Harness::run` just called `Harness::step` 3 times. If that
wasn't enough, tests would often call run multiple times so all
animations would finish properly.
Also, I introduced `HarnessBuilder::with_step_dt` to customize with how
big of a dt each frame is called. I set the default to 1.0 / 6.0 (~6fps)
so we don't waste cpu in tests waiting on animations.
`HarnessBuilder::max_steps` allows us to control how many steps
`Harness::run` should run before panicing.
The default is 6, so we run for up to 1.0 logical seconds (six frames at
6 fps), which should be enough to finish most animations.
Turns out a lot of snapshots where rendered before fully shown and had a
light opacity, those are now fixed.

Closes <https://github.com/emilk/egui/issues/3862>.
Factoring the `bool` members of `Response` into a bitfield, the size of
`Response` is now 96 bytes (down from 104).
I gave `Sense` the same treatment, however this has no effects on
`Response` due to padding. I've decided not to pursue `PointerState`, as
it is quite large (_many_ members that are sized and aligned to
multiples of 8 bytes), so I don't expect any noticeable benefit from
making handful of `bool`s slightly leaner.
In any case, the changes to `Sense` are already quite a bit more
intrusive than those to `Response`.
The previous implementation overloaded the names of the attributes
`click` and `drag` with similarly named methods that _construct_ `Sense`
with the corresponding flag set. Now, that the attributes can no longer
be accessed directly, I had to introduce methods with new names
(`senses_click()`, `senses_drag()` and `is_focusable()`). I don't think
this is the cleanest solution: the old methods are essentially redundant
now that the named constants like `Sense::CLICK` exist. I did however
not want to needlessly break backwards compatibility.
I am happy to revert it (or go further 🙂) if there are concerns.

Unfortunately i had several issues:
- Some snapshot-tests didn't run successfully on osx. diff shows errors
around fonts or missing menu items)
- cargo clippy doesn't run successfully (egui_kittest cannot find `wgpu`
and `image`)
- ./scripts/check.sh had other issues on my system (env: python: No such
file or directory), even if python3 can be called via python in my shell
Is there a system independent, standard way to run these tools (e.g. via
Docker?)
I submit the pr anyway, because there changes are very simple and
shouldn't cause issues.
