title: Finding objects under mouse in a JSVGCanvas from Batik
body: <p>I have a JSVGCanvas object from the Batik library from java.  In my application, I am rendering several objects in a schematic.  I require to know what component is below the mouse so I can render an appropiate tooltip and description that I am rendering from an external source.</p>
  
  <p>My question is, how can I determine what objects are below the cursor at any given time?</p>
