The three methods for showing a `Panel` are now:
* `panel.show`: always show the panel.
* `panel.show_collapsible`: show or hide the panel, with a slide
animation in between.
* `Panel::show_switched`: animate between two different panels: a
thin/collapsed one and a thick/expanded one.

## 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` ?
egui never accesses the `FontDefinitions`' member fields mutably, except
in `fonts_tweak_ui` where it cloned the `FontDefinitions` object anyway.
This patch reduces system memory consumption for shared font
definitions.
And also removes some overhead from copying (e.g. for the per
`pixel_per_points` font atlas)
Also it allows to keep a copy of the font definitions outside of egui.
In my App that uses international fonts:
Before:
New:
Note: If `Arc` is not wanted, then it could ofc be abstracted away.
I know this is quite a breaking change API wise, but would like to hear
your opinion.
make it easier to add fonts.
For example if I want to add a custom FontFamily or if the user wants to
add a Chinese fallback

This allows license checking tools to omit the OFL and UFL licenses when
`default_fonts` are turned off.
There was some discussion of versioning on the original issue; I have
chosen to label this version as `0.28.1` to match the other crates.
Happy to adjust the version as needed.

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(…)`.

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()
};
```
* 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
* 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
