 * An internal dispatcher for guice-servlet registered servlets and filters.
 * By default, we assume a Guice 1.0 style servlet module is in play. In other
 * words, we dispatch directly to the web.xml pipeline after setting up scopes.
 * <p>
 * If on the other hand, {@link ServletModule} is used to register managed
 * servlets and/or filters, then a different pipeline is bound instead. Which,
 * after dispatching to Guice-injected filters and servlets continues to the web.xml
 * pipeline (if necessary).
