    //------------------------

    // Pinnacle does not manage layouts compositor-side.
    // Instead, it delegates computation of layouts to your config,
    // which provides an interface to calculate the size and location of
    // windows that the compositor will use to position windows.
    //
    // If you're familiar with River's layout generators, you'll understand the system here
    // a bit better.
    //
    // The Rust API provides two layout system abstractions:
    //     1. Layout managers, and
    //     2. Layout generators.
    //
    // ### Layout Managers ###
    // A layout manager is a struct that implements the `LayoutManager` trait.
    // A manager is meant to keep track of and choose various layout generators
    // across your usage of the compositor.
    //
    // ### Layout generators ###
    // A layout generator is a struct that implements the `LayoutGenerator` trait.
    // It takes in layout arguments and computes a vector of geometries that will
    // determine the size and position of windows being laid out.
    //
    // There is one built-in layout manager and five built-in layout generators,
    // as shown below.
    //
    // Additionally, this system is designed to be user-extensible;
    // you are free to create your own layout managers and generators for
    // maximum customizability! Docs for doing so are in the works, so sit tight.

    // Create a `CyclingLayoutManager` that can cycle between layouts on different tags.
    //
    // It takes in some layout generators that need to be boxed and dyn-coerced.
