title: resize svg icon for google map marker
body: <p>I'm having problem with icon resizing in google map.
  I have an svg file for make it responsive.</p>
  
  <p>this is how I call the svg file</p>
  
  <pre><code>MyGreenSVG = {
      url: 'greenFill.svg',
      size: new google.maps.Size(20, 35)
  };
  </code></pre>
  
  <p>the property: size doesn't change the size of my icon, but only crop it.
  the only way is to change the width and height in my svg file, and make 2 versions of it.
  so I loose the interest of using svg...</p>
  
  <p>this is a preview of my svg file : </p>
  
  <pre><code>&lt;svg version="1.1"
  x="0px" y="0px" width="41.8px" height="74px" viewBox="0 0 41.8 74" enable-background="new 0 0 41.8 74" xml:space="preserve"&gt;
  </code></pre>
