Generic wrapper around a view.

Default implementation forwards all calls to the child view. Overrides some methods as desired.

You can use the wrap_impl! macro to define with_view and with_view_mut for you.

Wraps the required_size method.

Wraps the on_event method.

Wraps the layout method.

Wraps the take_focus method.

Wraps the find method.
