       No, watermark is at bottom-right of IFRAME.
       If iframe is 120% of container, and centered?
       Container overflow hidden.
       We want bottom-right corner of FRAME to be OUTSIDE container.
       Default iframe is top-left 0.
       If we make it 120%, it extends to right and bottom.
       So normally watermark is at 100% W, 100% H.
       With 120%, it is at 120% W, 120% H relative to container.
       So it is HIDDEN. (Container clips at 100%).
       So plain width: 120%; height: 120%; is enough if aligned top-left.
       But we want to center the content probably.
       Let's use negative margin to center:
       margin-left: -10%; margin-top: -10%;
       This puts the center of iframe at center of container.
       Bottom-right of iframe is now at 110% W of container.
       So watermark is hidden.
