* 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.
