<h1>Zoom delta test.</h1>
|
|
<p>Zooming with touch zoom, box zoom or flyTo then <code>map.stop()</code> must make the zoom level snap to the value of the <code>zoomSnap</code> option. Zoom interactions (keyboard, mouse wheel, zoom control buttons must change the zoom by the amount in the <code>zoomDelta</code> option.</p>
