Enable these new clippy lints and fix all warnings:
* `format_push_string` — use `write!` instead of `s += &format!(…)` to
avoid extra allocations
* `ignored_unit_patterns` — use `()` instead of `_` when matching unit
* `missing_fields_in_debug` — ensure manual `Debug` impls account for
all fields
* `needless_raw_string_hashes` — remove unnecessary `r#` on string
literals
* `ref_option` — prefer `Option<&T>` over `&Option<T>` in function
signatures

## 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` ?
The closure passed to `eframe::run_native` now returns a `Result`,
allowing you to return an error during app creation, which will be
returned to the caller of `run_native`.
This means you need to wrap your `Box::new(MyApp::new(…))` in an
`Ok(…)`.

Raw mouse movement is unaccelerated and unclamped by screen boundaries,
and does not relate to any position on the screen.
It is useful in certain situations such as draggable values and 3D
cameras, where screen position does not matter.

Added `Event::MouseMoved` for integrations to supply raw mouse movement.
Added `Response:drag_motion` to get the raw mouse movement, but will
fall back to delta in case the integration does not supply it.
Nothing should be breaking, but third-party integrations that can send
`Event::MouseMoved` should be updated to do so.
Based on #1614 but updated to the current version, and with better
fallback behaviour.
* Closes#1611
* Supersedes #1614

This PR replaces a bunch of options in `eframe::NativeOptions` with
`egui::ViewportBuilder`. For instance:
``` diff
let options = eframe::NativeOptions {
- initial_window_size: Some(egui::vec2(320.0, 240.0)),
- drag_and_drop_support: true,
+ viewport: egui::ViewportBuilder::default()
+ .with_inner_size([320.0, 240.0])
+ .with_drag_and_drop(true),
centered: true,
..Default::default()
};
```
* Revert "fix all clippy lints and remove them from allow list in cranky (#2419)"
This reverts commit 930ef2db38.
* Explain the cranky lints better
* Add Color32::gamma_multiply
* Remove unused pub use
* Remove non-existing crate category
* Improve color test with more lines
* Improve the look of thin lines, making them look weaker
Before they looked were too strong for the thickness.
* Use asserts for shader compilations
* Update changelogs
* eframe::run_native: return errors instead of crashing
* Detect and handle glutin errors
* egui_demo_app: silence wgpu log spam
* Add trace logs for why eframe is shutting down
* Fix: only save App state once on Mac
* Handle Winit failure
* Log where we load app state from
* Don't panic on zero-sized window
* Clamp loaded window size to not be too tiny to see
* Simplify code: more shared code in window_builder
* Improve code readability
* Fix wasm32 build
* fix android
* Update changelog
* Re-implement PaintCallbacks With Support for WGPU
This makes breaking changes to the PaintCallback system, but makes it
flexible enough to support both the WGPU and glow backends with custom
rendering.
Also adds a WGPU equivalent to the glow demo for custom painting.
* Move examples out of eframe/examples into examples/
Give each example a `Cargo.toml` and `src/main.rs`.
This makes it easier for people to use as templates.
* Update README.md with more deps needed on vanilla Ubuntu
* Install libgtk-3-dev on CI, hoping that will fix something
