This is more general, and necessary if the custom theming is dynamically generated. Iced's builtin theme also uses `Box`ed `Fn`, or `Rc` where clone is required, so this seems reasonable. Only `Text` is left using `fn`, since it needs to be `Copy`. Hopefully that can be changed in Iced at some point. `::custom` methods are added to make these variants a little more convenient to construct. This replaces a couple `From` implementations, which are potentially problematic with a generic.
