	 * When the window is loaded:

	 * Ideally, it is not considered best practise to attach more than a
	 * single DOM-ready or window-load handler for a particular page.
	 * Although scripts in the WordPress core, Plugins and Themes may be
	 * practising this, we should strive to set a better example in our own work.
