  • ie:  You can set the mapView to allow zooms 1-20, even if your tile source can only provide 2-14.  
    
    Limitations:
      Allowing too much overzoom results in poor images due to high magnification scaling.
      Allowing too much underzoom results in poor performance and eventually hard crashes due to memory and graphics limitations.  In general, on a 3G, you
        can only allow 1 level of underzoom.    3GS can do more.  Customize to your application, there is a friendly assert to this affect.
    
      Unique tilesources should no longer provide minZoom/maxZoom/tileSideLength functions as these values should come from the RMFractal projection.  Instead set custom values in the init.
      I have updated all checked in sources, but if you have your own custom source, it will need an easy tweek or two.
