Hey! I am not sure if this is something that's been considered before
and decided against (I couldn't find any PR's or issues).
This change removes the internal profiling macros in library crates and
the `puffin` feature and replaces it with similar functions in the
[profiling](https://github.com/aclysma/profiling) crate. This crate
provides a layer of abstraction over various profiler instrumentation
crates and allows library users to pick their favorite (supported)
profiler.
An additional benefit for puffin users is that dependencies of egui are
included in the instrumentation output too (mainly wgpu which uses the
profiling crate), so more details might be available when profiling.
A breaking change is that instead of using the `puffin` feature on egui,
users that want to profile the crate with puffin instead have to enable
the `profile-with-puffin` feature on the profiling crate. Similarly they
could instead choose to use `profile-with-tracy` etc.
I tried to add a 'tracy' feature to egui_demo_app in order to showcase ,
however the /scripts/check.sh currently breaks on mutually exclusive
features (which this introduces), so I decided against including it for
the initial PR. I'm happy to iterate more on this if there is interest
in taking this PR though.
Screenshot showing the additional info for wgpu now available when using
puffin

Adds support for mipmaps in the `glow` backend.
Should be possible to implement for `wgpu` in the future as well, but
requires a custom compute kernel.
This solves a GL_INVALID_ENUM error common on Windows (occurs on my
Windows 10 machine with a GTX 1070 Ti).

ARB_framebuffer_SRGB is entirely unsupported on WebGL, hence why latest
egui (master branch) doesn't try to disable SRGB framebuffers on wasm32
and this PR's code doesn't even check for ARB_framebuffer_sRGB on
wasm32.
* For <servo/servo#30782>
Exposes support in both glow and wgpu for texture wrap modes
This would be breaking for manual creations of TextureOptions but would
work with the current TextureOptions::NEAREST and LINEAR without change,
keeping those clamp to edge
I wasn't sure how best to expose the options to the user and added
consts for LINEAR_REPEAT LINEAR_MIRRORED_REPEAT NEAREST_REPEAT
NEAREST_MIRRORED_REPEAT
This does not include wrap mode clamp to border as it worked fine with
glow but with wgpu it panics due to Features
Features(ADDRESS_MODE_CLAMP_TO_BORDER) are required but not enabled on
the device, and I thought it was probably best not to try to enable that
feature, but happy to include that functionality also if that is okay to
be toggled

* 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.

(new PR description written by @emilk)
## Overview
This PR introduces the concept of `Viewports`, which on the native
eframe backend corresponds to native OS windows.
You can spawn a new viewport using `Context::show_viewport` and
`Cotext::show_viewport_immediate`.
These needs to be called every frame the viewport should be visible.
This is implemented by the native `eframe` backend, but not the web one.
## Viewport classes
The viewports form a tree of parent-child relationships.
There are different classes of viewports.
### Root vieport
The root viewport is the original viewport, and cannot be closed without
closing the application.
### Deferred viewports
These are created with `Context::show_viewport`.
Deferred viewports take a closure that is called by the integration at a
later time, perhaps multiple times.
Deferred viewports are repainted independenantly of the parent viewport.
This means communication with them need to done via channels, or
`Arc/Mutex`.
This is the most performant type of child viewport, though a bit more
cumbersome to work with compared to immediate viewports.
### Immediate viewports
These are created with `Context::show_viewport_immediate`.
Immediate viewports take a `FnOnce` closure, similar to other egui
functions, and is called immediately. This makes communication with them
much simpler than with deferred viewports, but this simplicity comes at
a cost: whenever tha parent viewports needs to be repainted, so will the
child viewport, and vice versa. This means that if you have `N`
viewports you are poentially doing `N` times as much CPU work. However,
if all your viewports are showing animations, and thus are repainting
constantly anyway, this doesn't matter.
In short: immediate viewports are simpler to use, but can waste a lot of
CPU time.
### Embedded viewports
These are not real, independenant viewports, but is a fallback mode for
when the integration does not support real viewports. In your callback
is called with `ViewportClass::Embedded` it means you need to create an
`egui::Window` to wrap your ui in, which will then be embedded in the
parent viewport, unable to escape it.
## Using the viewports
Only one viewport is active at any one time, identified wth
`Context::viewport_id`.
You can send commands to other viewports using
`Context::send_viewport_command_to`.
There is an example in
<https://github.com/emilk/egui/tree/master/examples/multiple_viewports/src/main.rs>.
## For integrations
There are several changes relevant to integrations.
* There is a [`crate::RawInput::viewport`] with information about the
current viewport.
* The repaint callback set by `Context::set_request_repaint_callback`
now points to which viewport should be repainted.
* `Context::run` now returns a list of viewports in `FullOutput` which
should result in their own independant windows
* There is a new `Context::set_immediate_viewport_renderer` for setting
up the immediate viewport integration
* If you support viewports, you need to call
`Context::set_embed_viewports(false)`, or all new viewports will be
embedded (the default behavior).
## Future work
* Make it easy to wrap child viewports in the same chrome as
`egui::Window`
* Automatically show embedded viewports using `egui::Window`
* Use the new `ViewportBuilder` in `eframe::NativeOptions`
* Automatically position new viewport windows (they currently cover each
other)
* Add a `Context` method for listing all existing viewports

## Inspiration
- Godot because the app always work desktop or single_window because of
embedding
- Dear ImGui viewport system
## What is a Viewport
A Viewport is a egui isolated component!
Can be used by the egui integration to create native windows!
When you create a Viewport is possible that the backend do not supports
that!
So you need to check if the Viewport was created or you are in the
normal egui context!
This is how you can do that:
```rust
if ctx.viewport_id() != ctx.parent_viewport_id() {
// In here you add the code for the viewport context, like
egui::CentralPanel::default().show(ctx, |ui|{
ui.label("This is in a native window!");
});
}else{
// In here you add the code for when viewport cannot be created!
// You cannot use CentralPanel in here because you will override the app CentralPanel
egui::Window::new("Virtual Viewport").show(ctx, |ui|{
ui.label("This is without a native window!\nThis is in a embedded viewport");
});
}
```
This PR do not support for drag and drop between Viewports!
After this PR is accepted i will begin work to intregrate the Viewport
system in `egui::Window`!
The `egui::Window` i want to behave the same on desktop and web
The `egui::Window` will be like Godot Window
## Changes and new
These are only public structs and functions!
<details>
<summary>
## New
</summary>
- `egui::ViewportId`
- `egui::ViewportBuilder`
This is like winit WindowBuilder
- `egui::ViewportCommand`
With this you can set any winit property on a viewport, when is a native
window!
- `egui::Context::new`
- `egui::Context::create_viewport`
- `egui::Context::create_viewport_sync`
- `egui::Context::viewport_id`
- `egui::Context::parent_viewport_id`
- `egui::Context::viewport_id_pair`
- `egui::Context::set_render_sync_callback`
- `egui::Context::is_desktop`
- `egui::Context::force_embedding`
- `egui::Context::set_force_embedding`
- `egui::Context::viewport_command`
- `egui::Context::send_viewport_command_to`
- `egui::Context::input_for`
- `egui::Context::input_mut_for`
- `egui::Context::frame_nr_for`
- `egui::Context::request_repaint_for`
- `egui::Context::request_repaint_after_for`
- `egui::Context::requested_repaint_last_frame`
- `egui::Context::requested_repaint_last_frame_for`
- `egui::Context::requested_repaint`
- `egui::Context::requested_repaint_for`
- `egui::Context::inner_rect`
- `egui::Context::outer_rect`
- `egui::InputState::inner_rect`
- `egui::InputState::outer_rect`
- `egui::WindowEvent`

## Changes
</summary>
- `egui::Context::run`
Now needs the viewport that we want to render!
- `egui::Context::begin_frame`
Now needs the viewport that we want to render!
- `egui::Context::tessellate`
Now needs the viewport that we want to render!
- `egui::FullOutput`
```diff
- repaint_after
+ viewports
+ viewport_commands
```
- `egui::RawInput`
```diff
+ inner_rect
+ outer_rect
```
- `egui::Event`
```diff
+ WindowEvent
```
</details>
### Async Viewport
Async means that is independent from other viewports!
Is created by `egui::Context::create_viewport`
To be used you will need to wrap your state in `Arc<RwLock<T>>`
Look at viewports example to understand how to use it!
### Sync Viewport
Sync means that is dependent on his parent!
Is created by `egui::Context::create_viewport_sync`
This will pause the parent then render itself the resumes his parent!
#### ⚠️ This currently will make the fps/2 for every sync
viewport
### Common
#### ⚠️ Attention
You will need to do this when you render your content
```rust
ctx.create_viewport(ViewportBuilder::new("Simple Viewport"), | ctx | {
let content = |ui: &mut egui::Ui|{
ui.label("Content");
};
// This will make the content a popup if cannot create a native window
if ctx.viewport_id() != ctx.parent_viewport_id() {
egui::CentralPanel::default().show(ctx, content);
} else {
egui::Area::new("Simple Viewport").show(ctx, |ui| {
egui::Frame::popup(ui.style()).show(ui, content);
});
};
});
````
## What you need to know as egui user
### If you are using eframe
You don't need to change anything!
### If you have a manual implementation
Now `egui::run` or `egui::begin` and `egui::tessellate` will need the
current viewport id!
You cannot create a `ViewportId` only `ViewportId::MAIN`
If you make a single window app you will set the viewport id to be
`egui::ViewportId::MAIN` or see the `examples/pure_glow`
If you want to have multiples window support look at `crates/eframe`
glow or wgpu implementations!
## If you want to try this
- cargo run -p viewports
## This before was wanted to change
This will probably be in feature PR's
### egui::Window
To create a native window when embedded was set to false
You can try that in viewports example before:
[78a0ae8](78a0ae879e)
### egui popups, context_menu, tooltip
To be a native window
</details>

* Clear color values are not explicitely sent to the rendering backend as-is.
Previously, converting from Color32 to Rgba caused an srgb->linear conversion. This conversion is incorrect if the backbuffer doesn't perform automatic conversion from linear->srgb (lack of this conversion is generally what egui assumes!).

The Vivante GPU on many STM32MP1 based boards does not support sRGB
as an internal format.
Introduce a check for sRGB support and default to `RGBA8` internal format
if not supported.
Additionally the STM32MP1 needs to be checked for `GL_ARB_vertex_array_object`
