    * delivered and <i>not</i> bubbled to the page. This means that even if you
    * aren't interested in the message, no other parts of the page will get
    * a crack at the message.

-   * <code>

    *   RequestInputEvents(instance, PP_INPUTEVENT_CLASS_MOUSE);

    * Filtering input events requires significantly more overhead than just
    * delivering them to the instance. As such, you should only request
    * filtering in those cases where it's absolutely necessary. The reason is
    * that it requires the browser to stop and block for the instance to handle
    * the input event, rather than sending the input event asynchronously. This
    * can have significant overhead.
