Deprecate `egui_glium` - looking for new maintainer (#2668)
* Deprecate egui_glium - looking for new maintainer
egui_glium was the first backend of egui, and it served us well for
a long time, but we have long since moved on to glow and wgpu.
Not egui_glium is holding back an update to latest winit.
Since development on glium has long since been discontinued I will
therefore deprecate egui_glium with this PR.
The code is still there in the repository for a while longer,
but is no longer compiled.
If there is any interest in maintaining egui_glium, then fork it and
make a PR to remove the last egui_glium from this repository.
I will give you publish rights on crates.io.

### Official integrations
These are the official egui integrations:
* [`eframe`](https://github.com/emilk/egui/tree/master/crates/eframe) for compiling the same app to web/wasm and desktop/native. Uses `egui_glow` and `egui-winit`.
* [`egui_glium`](https://github.com/emilk/egui/tree/master/crates/egui_glium) for compiling native apps with [Glium](https://github.com/glium/glium).
* [`eframe`](https://github.com/emilk/egui/tree/master/crates/eframe) for compiling the same app to web/wasm and desktop/native. Uses `egui-winit` and `egui_glow` or `egui-wgpu`.
* [`egui_glow`](https://github.com/emilk/egui/tree/master/crates/egui_glow) for rendering egui with [glow](https://github.com/grovesNL/glow) on native and web, and for making native apps.
* [`egui-wgpu`](https://github.com/emilk/egui/tree/master/crates/egui-wgpu) for [wgpu](https://crates.io/crates/wgpu) (WebGPU API).
* [`egui-winit`](https://github.com/emilk/egui/tree/master/crates/egui-winit) for integrating with [winit](https://github.com/rust-windowing/winit).
* [`egui_glium`](https://github.com/emilk/egui/tree/master/crates/egui_glium) for compiling native apps with [Glium](https://github.com/glium/glium) (DEPRECATED - looking for new maintainer).
This crate depends on [`egui-winit`](https://github.com/emilk/egui/tree/master/crates/egui-winit).
## DEPRECATED - Looking for new maintainer
This crate is no longer being updated. If you are interested in keeping `egui_glium` updated, then fork it to its own repository, make a PR to the egui repo removing it, and then I will give you access to it on crates.io so you can publish new `egui_glium` crates.
