### Breaking changes:
Most settings in `NativeOptions` have been moved to `NativeOptions::viewport`, which uses the new `egui::ViewportBuilder`:

```diff
 let native_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),
     ..Default::default()
 };
```

`NativeOptions::fullsize_content` has been replaced with four settings: `ViewportBuilder::with_fullsize_content_view`, `with_title_shown`, `with_titlebar_shown`, `with_titlebar_buttons_shown`

`frame.info().window_info` is gone, replaced with `ctx.input(|i| i.viewport())`.

`frame.info().native_pixels_per_point` is replaced with `ctx.input(|i| i.raw.native_pixels_per_point)`.

Most commands in `eframe::Frame` has been replaced with `egui::ViewportCommand`, so So `frame.close()` becomes `ctx.send_viewport_cmd(ViewportCommand::Close)`, etc.

`App::on_close_event` has been replaced with `ctx.input(|i| i.viewport().close_requested())` and `ctx.send_viewport_cmd(ViewportCommand::CancelClose)`.

`eframe::IconData` is now `egui::IconData`.

`eframe::IconData::try_from_png_bytes` is now `eframe::icon_data::from_png_bytes`.

`App::post_rendering` is gone. Screenshots are taken with `ctx.send_viewport_cmd(ViewportCommand::Screenshots)` and are returned in `egui::Event` which you can check with:
``` rust
ui.input(|i| {
    for event in &i.raw.events {
        if let egui::Event::Screenshot { viewport_id, image } = event {
            // handle it here
        }
    }
});
```
