/// The trait that game implementations must fulfill to receive

    /// All game logic, physics, and state mutations should happen here.

    /// # Arguments
    ///
    /// - `f64` - The fixed delta time in seconds.

    /// Called once per animation frame after all accumulated updates have been processed.

    /// # Arguments
    ///
    /// - `f64` - The interpolation factor in the range 0.0 to 1.0.
