 * The input manager is the core of the system event processing.

 *

 * The input manager has two components.

 * The input manager has three components.

 *

 * 1. The InputReader class starts a thread that reads and preprocesses raw input events, applies

 *    policy, and posts messages to a queue managed by the InputDispatcherThread.

 * 2. The InputDispatcher class starts a thread that waits for new events on the

 *    queue and asynchronously dispatches them to applications.

 *    policy, and posts messages to a queue managed by the InputClassifier.

 * 2. The InputClassifier class starts a thread to communicate with the device-specific

 *    classifiers. It then waits on the queue of events from InputReader, applies a classification

 *    to them, and queues them for the InputDispatcher.

 * 3. The InputDispatcher class starts a thread that waits for new events on the

 *    previous queue and asynchronously dispatches them to applications.

 *

 * By design, the InputReader class and InputDispatcher class do not share any

 * internal state.  Moreover, all communication is done one way from the InputReader

 * into the InputDispatcherThread and never the reverse.  Both classes may interact with the

 * InputDispatchPolicy, however.
