   farlo vedere. Il riquadro quasi mai cade su pixel interi, quindi buco e video non coincidono e sul bordo
   destro o inferiore resta una striscia nera, soprattutto al caricamento, mentre i riquadri animati
   passano sopra il video. La maschera, senza effetti visibili, fa disegnare il video insieme alla pagina. */
