A lot of the `eframe` API is native-only or web-only. With this PR, only the parts that are implemented for each platform is exposed.
This means you'll need to add `#[cfg(target_arch = "wasm32")]` around code that uses the web-parts of the eframe API, and add `#[cfg(not(target_arch = "wasm32"))]` around the parts that are for native/desktop.
* Use dark-light on Mac and Windows
dark-light has a nasty problem on Linux: https://github.com/frewsxcv/rust-dark-light/issues/17
So we made dark-light opt-in in https://github.com/emilk/egui/pull/1437
This PR makes dark-light a default dependency again,
but only use it on Max and Windows.
This is controlled with the new NativeOptions::follow_system_theme.
If this isn't enabled, then NativeOptions::default_theme is used.
* Add eframe::WebOptions
This is a fix for the behaviour on macOS platforms where any egui app would use the dedicated GPU and consume more power than needed. Not all apps might have dedicated GPU requirements.
* 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.
* egui-winit: don't assume window available at init
On Android in particular we can only initialize render state once we
have a native window, after a 'Resumed' lifecycle event. It's still
practical to be able to initialize an egui_winit::State early on
so this adds setters for the max_texture_side and pixels_per_point
that can be called once we have a valid Window and have initialized
a graphics context.
On Wayland, where we need to access the Display for clipboard handling
we now get the Display from the event loop instead of a window.
* egui-wgpu: lazily initialize render + surface state
Enable the renderer and surface state initialization to be deferred
until we know that any winit window we created has a valid native window
and enable the surface state to be updated in case the native window
changes.
In particular these changes help with running on Android where winit
windows will only have a valid native window associated with them
between Resumed and Paused lifecycle events, and so surface creation
(and render state initialization) needs to wait until the first
Resumed event, and the surface needs to be dropped/recreated based on
Paused/Resumed events.
Based on https://github.com/hasenbanck/egui_wgpu_backend
`egui-wgpu` is now an official backend for `eframe` (opt-in).
Use the `wgpu` feature flag on `eframe` and the `NativeOptions::renderer` settings to pick it.
