This also includes minor refactoring

Personally, I'd be happier to have the icon be silently ignored on platforms where it isn't supported.
In its current form this is a feature gate footgun which makes it less likely that applications would support e.g. darwin or android out of the gate.
Additionally, it seems reasonable that we might in future support making this change the website favicon, perhaps behind a feature gate

This should probably use the tracing error! macro

Ideally we'd support create an icon from any image type supported by the image crate. I'm not sure which crate that support should live in, however.

I suppose if this used Cow<'static, [u8]> we could avoid the to_vec, in case another backend supported &'static [u8] icons for example
That being said, requiring the user to create the Vec to match the winit API is also reasonable.

If possible, I think it would be nice if we could load icons using the asset system (ex: make the window descriptor take a |
