Propagate error from EventLoop
creation
Inner panics could make it hard to trouble shoot the issues and for some users it's not desirable. The inner panics were left only when they are used to `assert!` during development. This reverts commit 9f91bc413fe20618bd7090829832bb074aab15c3 which reverted the original patch which was merged without a proper review. Fixes: #500.

- **Breaking:** `WINIT_UNIX_BACKEND` was removed in favor of standard `WAYLAND_DISPLAY` and `DISPLAY` variables.
|
||||
- **Breaking:** `EventLoop::new` and `EventLoopBuilder::build` now return `Result<Self, EventLoopError>`
|
||||
- On X11, set `visual_id` in returned `raw-window-handle`.
|
||||
- **Breaking:** on Wayland, dispatching user created wayland queue won't wake up the loop unless winit has event to send back.
|
||||
- Removed platform-specific extensions that should be retrieved through `raw-window-handle` trait implementations instead:

- On Web, remove unnecessary `Window::is_dark_mode()`, which was replaced with `Window::theme()`.
|
||||
- On Web, add `WindowBuilderExtWebSys::with_append()` to append the canvas element to the web page on creation.
|
||||
- On Windows, add `drag_resize_window` method support.
|
||||
- **Breaking** `run() ->!` has been replaced by `run() -> Result<(), RunLoopError>` for returning errors without calling `std::process::exit()` ([#2767](https://github.com/rust-windowing/winit/pull/2767))

|

- `RedrawRequested` is no longer guaranteed to be emitted after `MainEventsCleared`, it is now platform-specific when the event is emitted after being requested via `redraw_request()`.
|

- On Windows, `RedrawRequested` is now driven by `WM_PAINT` messages which are requested via `redraw_request()`
