There is a missing safety comment in bevy_render

[nicopap]

How can Bevy's documentation be improved?

bevy_render::view::window has a fairly large unsafe block with no safety comment.

bevy/crates/bevy_render/src/view/window.rs

Lines 240 to 242 in 9e8de2a

	let surface = render_instance
	.create_surface(&window.handle.get_handle())
	.expect("Failed to create wgpu surface");

The unsafe operation is render_instance.create_surface(…) (https://docs.rs/wgpu/latest/wgpu/struct.Instance.html#method.create_surface).

• The unsafe block could be limited to create_surface, the rest of the unsafe block doesn't uphold any invariants related to create_surface
• There should be a safety comment explaining why the RawWindowHandle passed to create_surface are valid. (to be fair, this seems particularly tricky, since I don't see any definition of "valid" in the wgpu doc)
