title: How to access the Overlay object boundingMapRect at the OverlayView?
body: <p>I'm trying to place images on top of Google Maps and I'm having trouble to fetch the overlay's boundingMapRect.
  The odd thing is that when I check the 'overlay' with the debugger the correct data   is
   there, but when I try to print it - its garbage. </p>
  
  <p>This is the printing code:</p>
  
  <pre><code>MKMapRect overlayRect = [self.overlay boundingMapRect];
  NSLog(@"\n\n\n");
  NSLog(@"drawMapRect: overlay: x: %f, y: %f, w: %f, h: %f", 
        MKMapRectGetMinX([overlay boundingMapRect]),
        MKMapRectGetMinY([overlay boundingMapRect]),
        MKMapRectGetWidth([overlay boundingMapRect]),
        MKMapRectGetHeight([overlay boundingMapRect]));
  NSLog(@"drawMapRect: boundingMapRect x: %f, boundingMapRect y: %f, boundingMapRect w: %f, boundingMapRect h: %f",
        [overlay boundingMapRect].origin.x,
        [overlay boundingMapRect].origin.y,
        [overlay boundingMapRect].size.width,
        [overlay boundingMapRect].size.height);
  NSLog(@"drawMapRect: boundingMapRect x: %f, boundingMapRect y: %f, boundingMapRect w: %f, boundingMapRect h: %f",
        self.overlay.boundingMapRect.origin.x,
        ((MKOverlayView *)self).overlay.boundingMapRect.origin.y,
        [overlay boundingMapRect].size.width,
        [overlay boundingMapRect].size.height);
  </code></pre>
  
  <p>It is placed at </p>
  
  <pre><code>- (void)drawMapRect:(MKMapRect)mapRect zoomScale:(MKZoomScale)zoomScale inContext:(CGContextRef)context.
  </code></pre>
  
  <p>Any help would be great.
  A small example of image drawing over a map with Core Graphics will be awesome.</p>
  
  <p>Thanks,
