title: google map zoom after directions
body: <p>I am using google maps in order to give some directions from one point to another.</p>
  
  <p>Although, I have set the zoom of the map to 15 the zoom changes after the response of the direction request in order probably to fit the directions into the map.</p>
  
  <p>Does anyone nows how to keep the zoom constant at 15. and focus at the first point?</p>
