## Summary
- Ignore raw device mouse motion unless the window is focused and the
pointer is inside it
- Also handles pointers starting down and then moving into or out of the
window (drag & drop)
- Prevents global mouse motion from triggering continuous repaint loops
- Applies to both glow and wgpu backends
## Testing
- I ran the check script, nothing seemed to fail

* [x] I have followed the instructions in the PR template
`get_proc_address` was introduced in #4145, but its lifetime was
designed to be tied to the lifetime `'s` of `CreationContext`. This
means that using `get_proc_address` outside the lifetime of
`CreationContext` is undefined behavior. This contradicts the original
intent behind introducing `get_proc_address`, as this API is intended
for integration with external libraries that cannot easily guarantee
alignment with egui's lifetimes. This PR changes the type of
`get_proc_address` from a reference to an `Arc`, decoupling its lifetime
from `CreationContext` to achieve safer memory management.

## What
This deprecates `eframe::App::update` and replaces it with two new
functions:
```rs
pub trait App {
/// Called just before `ui`, and in the future this will
/// also be called for background apps when needed.
fn logic(&mut self, ctx: &egui::Context, frame: &mut Frame) { }
/// Show your user interface to the user.
fn ui(&mut self, ui: &mut egui::Ui, frame: &mut Frame);
…
}
```
Similarly, `Context::run` is deprecated in favor of `Context::run_ui`.
`Plugin`s are now handed a `Ui` instead of just a `Context` in
`on_begin/end_frame`.
## TODO
…either in this PR or a later one
* [x] Deprecate `App::update`
* [x] Deprecate `Context::run`
* [x] Change plugins to get a `Ui`
* [x] Update kittest
* [x] Change viewports to get UI:s (`show_viewport_immediate` etc)
- https://github.com/emilk/egui/pull/7779
## Later PRs
* [ ] Deprecate `Panel::show`
* [ ] Deprecate `CentralPanel::show`
* [ ] Deprecate `CentralPanel` ?
### What
From the [lint
description](https://rust-lang.github.io/rust-clippy/master/index.html?search=or_fu#or_fun_call):
> The function will always be called. This is only bad if it allocates
or does some non-trivial amount of work.
But also:
> If the function has side-effects, not calling it will change the
semantic of the program, but you shouldn’t rely on that.
>
> The lint also cannot figure out whether the function you call is
actually expensive to call or not.
Still worth it to keep our happy paths clean, imo.
This combines `SidePanel` and `TopBottomPanel` into a single `Panel`.
The old types are still there as type aliases, but are deprecated.
`.min_width(…)` etc are now called `.min_size(…)` etc.
Again, the old names are still there, but deprecated.

* Closes https://github.com/emilk/egui/issues/5889
See the above issue for motivation.
To use glow instead, disable the default features of `eframe` and opt-in
to `glow`.
This also changes egui.rs to use wgpu, which means WebGPU when
available, and WebGL otherwise
* Part of https://github.com/emilk/egui/issues/5889
* Closes https://github.com/emilk/egui/issues/7106
This changes the `eframe/wgpu` feature to also enable all the `default`
features of `wgpu` and `egui-wgpu`. This makes switching `eframe`
backend from `glow` to `wgpu` a lot easier.
To get the old behavior (depend on `wgpu` but you must opt-in to all its
features), use the new `wgpu_no_default_features` feature.
* Closes#7657
* [x] I have followed the instructions in the PR template
On native this uses a new "touch phase" parameter of the mouse wheel
event to know if a scroll action is done.

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
https://github.com/user-attachments/assets/a621dac9-b7c3-426a-968b-dc73c5702eea
* Closes https://github.com/emilk/egui/issues/7402
* [x] I have followed the instructions in the PR template
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.
