              * -- {-> / <-} for zoom in

              * - One 'max move' functions, used to compute the max delta at which the operation can move a
              * range, according to a max range. For exemple, for a range of {1, 5} and a max range of {0, 10},
              * max deltas will be:
              * -- {0, 4} for pan left
              * -- {6, 10} for pan right
              * -- {3, 3} for zoom in
