     * Initializes resources like WebWorkers that can be shared across maps to lower load
     * times in some situations. `mapboxgl.workerUrl` and `mapboxgl.workerCount`, if being
     * used, must be set before `prewarm()` is called to have an effect.
     *
     * By default, the lifecycle of these resources is managed automatically, and they are
     * lazily initialized when a Map is first created. By invoking `prewarm()`, these
     * resources will be created ahead of time, and will not be cleared when the last Map
     * is removed from the page. This allows them to be re-used by new Map instances that
     * are created later. They can be manually cleared by calling
     * `mapboxgl.clearPrewarmedResources()`. This is only necessary if your web page remains
     * active but stops using maps altogether.
     *
     * This is primarily useful when using GL-JS maps in a single page app, wherein a user
     * would navigate between various views that can cause Map instances to constantly be
     * created and destroyed.
