The ESRI Silverlight and WPF API's both have a Map.SnapToLevels property that can be set on or off. It "gets or sets whether zooming will snap to scale levels if the map contains cached layers". But with the JS API, you always snap to levels and there appears to be no way to turn that behavior off. Is there a way to disable the snap to levels behavior in the JS API?
Or can someone provide the rationale behind ESRI's decision to not include that property in the JS API? (I'd like to be able to explain why I cannot provide the same type of zooming in JS API as with WPF API.)
