title: Min/max zoom level in OpenLayers
body: <p>I'm using OpenLayers to display a map in a web page. I am using tiles from CloudMade, but the same issues occur with the Mapnik tiles from OpenStreetMap.</p>
  
  <p>I'm trying to restrict the map so that the user cannot zoom all the way out to world view -- I want them to stay at roughly a city level zoom at minimum.</p>
  
  <p>I have tried using the <code>minZoomLevel</code> / <code>maxZoomLevel</code> / <code>numZoomLevels</code> properties; only the <code>maxZoomLevel</code> and <code>numZoomLevels</code> properties seem to work, whereas the <code>minZoomLevel</code> property seems to be completely ignored.</p>
  
  <p>Is there another way to accomplish this?</p>
