 programming techniques. The <code>input_events</code> example is used to
 illustrate how your module can react to keyboard and mouse input
 event.  The <code>mouse_lock</code> example is used to illustrate how your module
 can react to view change events. You can find these examples in the
 <code>/pepper_&lt;version&gt;/examples/api/input_event</code> and
 <code>/pepper_&lt;version&gt;/examples/api/mouse_lock</code> directories in the Native Client
 SDK.  There is also the ppapi_simple library that can be used to to implement
 most of the boiler plate.  The <code>pi_generator</code> example in
 <code>/pepper_&lt;version&gt;/examples/demo/pi_generator</code> uses ppapi_simple to manage
 view change events and 2D graphics.</p>

 <p><code>HandleInputEvent()</code> in this example runs on the main module thread.
 However, the bulk of the work happens on a separate worker thread (see
 <code>ProcessEventOnWorkerThread</code>). <code>HandleInputEvent()</code> puts events in
 the <code>event_queue_</code> and the worker thread takes events from the
 <code>event_queue_</code>. This processing happens independently of the main
 thread, so as not to slow down the browser.</p>
