Lay the slider controls over the picture like the Kant-IT hero in 1.11.4

Round white arrows left and right, dots bottom right with the active one as
an accent bar, a small pause button and no counter - the design of the hero
slider on kant-it.de. Slider and controls share a positioned shell; arrows
hide on phones. New style property for the active dot colour.
