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

    /// Performs an action on the chart.
