This appears to have been 'consumed' by the viewport changes at one
point (by updating `viewport_info`), but this is no longer the case. We
should avoid marking this as 'consumed', so that applications know to
continue processing this event after passing it to egui.

To work around a Safari limitation, we run the app logic in the event
handler of copy, cut, and mouse up and down.
Previously the output of that frame was discarded, but in this PR it is
now saved to be used in the next requestAnimationFrame.
The result is noticeable more distinct clicks on buttons (one more frame
of highlight)
Bonus: also fix auto-save of a sleeping web app
* Fixes https://github.com/rerun-io/rerun/issues/4297
* tested against a very hasty and incomplete port of egui/trunk, found
[here](https://github.com/rerun-io/rerun/tree/andreas/experimental-egui-trunk)
In rare cases in can happen that the viewport returned by
`PaintCallbackInfo` is outside the bounds of the screen.
for at least [wgpu/webgpu in
particular](https://www.w3.org/TR/webgpu/#dom-gpurenderpassencoder-setviewport)
this is invalid usage, other backends might be affected as well.
Since this happened due to a float rounding error (in one repro case I
had I got (width==1126.5625) + (offset=715.4376) = 1842.0001 for a
resolution of 1842) I decided to do away with fractional values on the
viewport alltogether. They _technically_ make sense since a viewport is
only specifying the NDC to pixel coordinate conversion, but practically
this may lead to surprising sub-sampling issues.

You can now zoom any egui app by pressing Cmd+Plus, Cmd+Minus or Cmd+0,
just like in a browser. This will change the current `zoom_factor`
(default 1.0) which is persisted in the egui memory, and is the same for
all viewports.
You can turn off the keyboard shortcuts with `ctx.options_mut(|o|
o.zoom_with_keyboard = false);`
`zoom_factor` can also be explicitly read/written with
`ctx.zoom_factor()` and `ctx.set_zoom_factor()`.
This redefines `pixels_per_point` as `zoom_factor *
native_pixels_per_point`, where `native_pixels_per_point` is whatever is
the native scale factor for the monitor that the current viewport is in.
This adds some complexity to the interaction with winit, since we need
to know the current `zoom_factor` in a lot of places, because all egui
IO is done in ui points. I'm pretty sure this PR fixes a bunch of subtle
bugs though that used to be in this code.
`egui::gui_zoom::zoom_with_keyboard_shortcuts` is now gone, and is no
longer needed, as this is now the default behavior.
`Context::set_pixels_per_point` is still there, but it is recommended
you use `Context::set_zoom_factor` instead.
* Closes https://github.com/emilk/egui/issues/3494
This makes sure it is always up-to-date.
Previously (years back) this caused a deadlock on Mac, but this seems to
have been fixed
This is required for Rust 1.72 (for unknown reasons; see
https://github.com/emilk/egui/pull/3595), but also for updating to glow
0.13, where the `glow::Context` is not longer `Sync+Send`
* Closes <https://github.com/emilk/egui/issues/3480>
I've tested this on Safari and Chrome on macOS Sonoma 14.0.
Could be improved to only call `event.preventDefault()` if
`runner.logic()` actually performed a copy, but I don't see a way to get
that information out with the current API.
* Closes#1974

Part 1 of 2 of adding a better API for egui_plot's auto-bounds feature.
In this PR:
- change the `Plot` builder struct field to `default_auto_bounds` (was
`auto_bounds`)
- change the `Plot` state field to `auto_bounds` (was `bounds_modified`)
- minor improvements to `Vec2b`

Closes <https://github.com/emilk/egui/issues/3576>.
Introduced in the recent multi-viewports work, we accidentally recreated
the wgpu surfaces every frame. This is now fixed.
I found this while improving the profiling of `eframe`
* Part of https://github.com/emilk/egui/issues/3556
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()
};
```
* Part of https://github.com/emilk/egui/issues/3556
## In short
You now almost never need to use `eframe::Frame` - instead use
`ui.input(|i| i.viewport())` for information about the current viewport
(native window), and use `ctx.send_viewport_cmd` to modify it.
## In detail
This PR removes most commands from `eframe::Frame`, and replaces them
with `ViewportCommand`.
So `frame.close()` becomes
`ctx.send_viewport_cmd(ViewportCommand::Close)`, etc.
`frame.info().window_info` is now also gone, replaced with `ui.input(|i|
i.viewport())`.
`frame.info().native_pixels_per_point` is replaced with `ui.input(|i|
i.raw.native_pixels_per_point)`.
`RawInput` now contains one `ViewportInfo` for each viewport.
Screenshots are taken with
`ctx.send_viewport_cmd(ViewportCommand::Screenshots)` and are returned
in `egui::Event` which you can check with:
``` ust
ui.input(|i| {
for event in &i.raw.events {
if let egui::Event::Screenshot { viewport_id, image } = event {
// handle it here
}
}
});
```
### Motivation
You no longer need to pass around the `&eframe::Frame` everywhere.
This also opens the door for other integrations to use the same API of
`ViewportCommand`s.

Closes <https://github.com/emilk/egui/issues/3474>.
The goal is to host the egui web-demo on its own `gh-pages` branch, and
have the CI build and publish a new demo on each merged CI.
Let's see if I can get this to work…
