title: How to combine view position with animation?
body: <p>I want to implement a "track up" map view, where the current position is not in the center of the map but 1/4 of the map height from the bottom (like standard navigation systems are in track up mode).
  I found this to be working with [centerOn] (<a href="https://openlayers.org/en/latest/apidoc/module-ol_View-View.html#centerOn" rel="nofollow noreferrer">https://openlayers.org/en/latest/apidoc/module-ol_View-View.html#centerOn</a>) defining the current GPS coordinates as "coordinate" and the "position" as width/2 and 1/4 of the map height just fine.</p>
  
  <p>Now, I want to add animation to this, to have a smooth transition between the GPS updates.</p>
  
  <p>I have tried this with [animate] (<a href="https://openlayers.org/en/latest/apidoc/module-ol_View-View.html#animate" rel="nofollow noreferrer">https://openlayers.org/en/latest/apidoc/module-ol_View-View.html#animate</a>), which does look really good from an animation perspective, but can't be positioned at the 1/4 height.
  Any idea how to combine both?</p>
