/**
 * Checks whether the generation of the HTTP response containing the SVG document has been aborted
 * by the user. This method makes the assumption that if the root cause of the given IOException
 * is an instance of TransformerException the operation has been canceled. Of course this
 * assumption might hide other reasons for why this kind of exception might have been thrown, but
 * it's the main reason./*from  w w w  .  j ava  2s .  c o m*/
 * <p>
 * There's a problem that makes it cumbersome to reliably detect if the generation of the response
 * has been canceled: The actual exception type at the bottom of the stack of Throwables that make
 * up the given IOException is a java.net.SocketException which in turn is probably wrapped by app
 * server specific exception types. These are then wrapped by exceptions of the various frameworks
 * that are used to write the SVG document to the HTTP response. For example, on Tomcat the stack
 * (from top to bottom) looks like the following:
 * <ul>
 * <li>java.io.IOException</li>
 * <li>javax.xml.transform.TransformerException</li>
 * <li>org.xml.sax.SAXException</li>
 * <li>org.apache.catalina.connector.ClientAbortException</
 * <li>java.net.SocketException</li>
 * </ul>
 * Therefore the above assumption is made for brevity.
 * 
 * @param ex
 *          The IOException that might indicate that the operation has been cancelled.
 * @return {@code true}, if the operation has probably been cancelled, {@code false} otherwise.
