Key input issue on mac

[toyboot4e]

winit has key input issue on macOS: rust-windowing/winit#1470

It says that macOS Accesibility prevents key inputs from going as DeviceEvents. So, on macOS, keyboard input events can only be captured as WindowEvent, unless somehow configuring Accesibility.

I made a commit to enable key input on macOS in the 3rd_person example: toyboot4e@2f2dafe. I can make such changes and make a PR, but I'm not sure if it's good to get key input as WindowEvent.

This is sad, WindowEvent is bad because it requires mouse to be inside window bounds to get any events from it, so it is suitable only for full screen mode. However it seems that there is no other solutions, so yeah PR would be nice, but I'd add #[cfg(target_os="macos")] to WindowEvent branch and #[cfg(not(target_os="macos"))] to DeviceEvent branch, so to use DeviceEvent where possible and WindowEvent otherwise.

Does it? My creature walks with WASD when my mouse is not on the window (if the window has focus). So I'm not seeing any particular problem on macOS. Hope this is a good news (or not on Windows?).

Keyboard input is working, right, mouse events won't come if cursor is outside window.

[toyboot4e]

Mouse events are still available as DeviceEvents on macOS. How about handling mouse events via DeviceEvent while handling keyboard events via WindowEvent? Then we don't need #[cfg] branch.

If that's OK, I would make a PR and prepare for review.

Yeah, that sounds good.
