title: maxZoom and User Input
body: <p>I want to limit the users max zoom level with inputs (muse scroll etc.) and buttons. In other words, I limit the "maxZoom" to -lets say- level9. But I still want to be able to zoom to level10 in special conditions.
  When I set the maxZoom, it obviously does not let me zoom more in any way, so wht is my solution in this case?</p>
