title: iOS Google Maps API drawing overlapping circles
body: <p>I am wondering how to draw two circles using the Google Maps API and, if they overlap each other, if they would get drawn as one shape. </p>
  
  <p>I know how to draw circles, and I know if I drew 2 circles that overlapped that had a solid fill, I would get what I am trying to achieve.</p>
  
  <p>Problem: I want to draw circles that have a transparent fill as well as a solid stroke (border). So if 2 or more circles were to overlap, not only would the stroke overlap but the fill in the overlapping area would be darker.</p>
  
  <p>I would like the border overlap to not be visible as well as the overlapping region to remain the same color/transparency.</p>
  
  <p>Any ideas?</p>
