ExponentialZoomManager

class ExponentialZoomManager : AbstractSlideInputManager, ZoomManager(source)

An ExpZoomManager converts the sliding of any physical/virtual device/control into a zoom rate through an exponential function (in this way I am sure to not see negative values ;-). Zoom = base ^ (amount of slides / normalization value).
