3/// A command for a chart.
4///
5/// The commands are what a handle sends to a chart. They are the same
6/// actions a chart takes on itself — drawing a new option, resizing,
7/// performing an action — and they travel through a signal, the way
8/// the rest of euv talks to its parts.
9///
10/// The option is boxed: an option is thousands of bytes, and a queue
11/// of commands should not be as big as the options it carries.
12///
13/// Every variant carries data, and `#[derive(Default)]` needs one
14/// without any, so this enum has no default.
