/*
 * Kruhový slideshow – port WordPress komponenty (nggallery/gallery-circle-slideshow.php
 * + Assets/css/component.css + sass/components/_gallery.scss).
 * Vše je scopované pod .gallery-circle-slideshow, aby se styly nemíchaly se zbytkem webu.
 * Načítá se jen na stránce, kde se komponenta vyskytuje (viz GalleryCircleSlideshowLoader.cshtml).
 * Šipky jsou kreslené v CSS místo původního Entypo fontu, 3D flip je vždy zapnutý (moderní prohlížeče).
