User interface widgets
Widgets are defined using the Widget trait.
You can choose to implement widgets yourself, or you can use the built in widgets defined in this module.
Since the whole Component every time it is mutated,
most widgets need to keep track of some kind of state across rebuilds.
This is managed automatically by the component, identified by the key method.
When implementing custom widgets, you need to make sure that the returned u64 key is as unique as possible.
You also need to make sure that the custom widgets do not remember absolute layouts.
Widgets like Scroll can change the layout without needing a rebuild of the ui.
