Inconsistent naming of tree parameter in Widget trait

[mfreeborn]

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

https://docs.iced.rs/iced/advanced/trait.Widget.html

The provided methods of the Widget trait use the name _state, whereas the required methods use tree, and it is these names which the IDE uses when auto-completing new methods that I want to impl on the trait.

tree is nicer, because then I can write let state = tree.state.downcast_ref::<...>() without shadowing the original Tree.

For consistency, it would be nicer to rename occurrences of _state to _tree. Saves me having to rewrite the parameter's name in its entirety vs just deleting the leading underscore if I want to use it in my impl.

What is the expected behavior?
