Hey, I added an event listener on the [`popstate`
event](https://developer.mozilla.org/en-US/docs/Web/API/Window/popstate_event).
That fixed my issue

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.
Using physical window sizes leads to all kinds of fun stuff: winit
always uses scale factor 1.0 on start to convert it back to logical
pixels and uses these logical pixels to set min/max size for
non-resizeable windows. You're supposed to adjust size after getting a
scale change event if you're using physical sizes, but adjusting min/max
sizes doesn't seem to work on sway, so the window is stuck with an
incorrect size.
The scale factor we guessed might also be wrong even if there's only a
single display since it doesn't take fractional scale into account.
TL;DR: winit actually wants logical sizes in these methods (since
Wayland in general operates mostly on logical sizes) and converting them
back and forth is lossy.

* Closes#2875
* Closes https://github.com/emilk/egui/pull/3340
* [x] I have followed the instructions in the PR template
Adds `create_native`. Similiar to `run_native` but it returns an
`EframeWinitApplication` which is a `winit::ApplicationHandler`. This
can be run on your own event loop. A helper fn `pump_eframe_app` is
provided to pump the event loop and get the control flow state back.
I have been using this approach for a few months.

Currently eframe [calls
`prevent_default()`](962c7c7516/crates/eframe/src/web/events.rs (L307-L369))
for all copy / paste events on the
[*document*](962c7c7516/crates/eframe/src/web/events.rs (L88)),
making embedding an egui application in a page (e.g. an react
application) hard (as all copy & paste functionality for other elements
on the page is broken by this).
I'm not sure what the motivation for this is, if any.
This commit / PR adds a callback (`should_prevent_default`), similar to
`should_propgate_event`, that an egui application can use to overwrite
this behavior. It defaults to returning `true` for all events, to keep
the existing behavior.
I call `should_prevent_default` in every place that
`should_propagate_event` is called (which is not all places that
`prevent_default` is called!). I'm not sure for the motivation of not
calling `should_propagate_event` everywhere that `stop_propagation` is
called, but I kept that behavior for the `should_prevent_default`
callback too.
Please let me know if I'm missing some existing functionality that would
allow me to do this, or if there's a reason that we don't want
applications to be able to customize this (i.e. if there's a reason to
always `prevent_default` for all copy / paste events on the whole
document)
Enabled the `missing_assert_message` lint

Dear emilk,
Programs built with egui on Windows are terminating every hour on
average.
When this commit is applied, it works fine for about 3 to 6 hours on
average.
I've been testing it for over 6 months and have submitted multiple PRs
since 6 months ago,
but they haven't applied it yet.
Thank you.

This is not supported on the web and not yet on Wayland.
~~I also had to update `ring` and add an exception for `paste` being
unmaintained.~~ Has since been updated on master.

This PR handles pointer events and focus which did following changes:
- `element_from_point` and focus is now acquired from root node object
by using `get_root_node` from document or a shadow root.
- `TextAgent` is appended individually in each shadow root.
These changes handles pointer events and focus well in a web app that
are running in a shadow dom, or else the hover pointer actions and
keyboard input events are not triggered in a shadow dom.
Helpful for building embeddable/multi-view web-apps.

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.

Tested on
* [x] Chromium
* [x] Firefox
* [x] Safari
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.

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).

Native is already delayed by a frame because it calls
`handle_viewport_output` -> `egui_winit::process_viewport_commands`
after drawing. On web however, we process input including viewport
commands separately from drawing.
This adds an arbitrary frame delay mechanism for web and then uses this
with 1 frame delay always
Hey! I am not sure if this is something that's been considered before
and decided against (I couldn't find any PR's or issues).
This change removes the internal profiling macros in library crates and
the `puffin` feature and replaces it with similar functions in the
[profiling](https://github.com/aclysma/profiling) crate. This crate
provides a layer of abstraction over various profiler instrumentation
crates and allows library users to pick their favorite (supported)
profiler.
An additional benefit for puffin users is that dependencies of egui are
included in the instrumentation output too (mainly wgpu which uses the
profiling crate), so more details might be available when profiling.
A breaking change is that instead of using the `puffin` feature on egui,
users that want to profile the crate with puffin instead have to enable
the `profile-with-puffin` feature on the profiling crate. Similarly they
could instead choose to use `profile-with-tracy` etc.
I tried to add a 'tracy' feature to egui_demo_app in order to showcase ,
however the /scripts/check.sh currently breaks on mutually exclusive
features (which this introduces), so I decided against including it for
the initial PR. I'm happy to iterate more on this if there is interest
in taking this PR though.
Screenshot showing the additional info for wgpu now available when using
puffin
