title: Google maps rectangle selection tool: how to keep the rectangle displayed in keydragzoom library
body: <p>With the keydragzoom library, you can mouse drag over a map to make rectangle selection, see this example: <a href="http://google-maps-utility-library-v3.googlecode.com/svn/tags/keydragzoom/2.0.9/examples/events.html" rel="nofollow">http://google-maps-utility-library-v3.googlecode.com/svn/tags/keydragzoom/2.0.9/examples/events.html</a></p>
  
  <p>What I want is to use this as a selection tool, i.e. to select particular rectangle, and keep the rectangle (the selection) displayed. But the rectangle always dissapears after ending the mouse drag. Is there any way how to achieve this with this library?</p>
  
  <p>I tried to set <code>noZoom</code> option to <code>true</code>, but it didn't help. I know I can draw my own rectangle, but it would require to handle situations when selecting a new rectangle, etc. So I would like to do it within this library.</p>
