title: Change marker size in Google Maps API v2
body: <p>I'm trying to port my app to the brand new Google Maps API v2, but can't find how to change the size of the marker (some of my markers are smaller than default).  </p>
  
  <p>In v1, I used a <code>Drawable</code> which I scaled with <code>setBounds()</code> before adding it to the map.</p>
  
  <p>But now, in v2, I can't use a <code>Drawable</code>. I've to use <code>MarkerOptions().icon()</code>, which takes just a <code>BitmapDescriptor</code> (generated with a <code>BitmapDescriptorFactory</code>).</p>
  
  <p>Looking at the reference, there doesn't seem to be any support for setting or changing the <code>BitmapDescriptor</code> size.</p>
  
  <p>So, have I missed something, or is it just plain impossible to set the size for custom markers in this API version?</p>
