+/**
+ * This interface supplies all UI-specific behavior of the window manager. An
+ * instance of it is created by the window manager when it starts up, and allows
+ * customization of window layering, special window types, key dispatching, and
+ * layout.
+ *
+ * <p>Because this provides deep interaction with the system window manager,
+ * specific methods on this interface can be called from a variety of contexts
+ * with various restrictions on what they can do. These are encoded through
+ * a suffixes at the end of a method encoding the thread the method is called
+ * from and any locks that are held when it is being called; if no suffix
+ * is attached to a method, then it is not called with any locks and may be
+ * called from the main window manager thread or another thread calling into
+ * the window manager.
+ *
+ * <p>The current suffixes are:
+ *
+ * <dl>
+ * <dt> Ti <dd> Called from the input thread. This is the thread that
+ * collects pending input events and dispatches them to the appropriate window.
+ * It may block waiting for events to be processed, so that the input stream is
+ * properly serialized.
+ * <dt> Tq <dd> Called from the low-level input queue thread. This is the
+ * thread that reads events out of the raw input devices and places them
+ * into the global input queue that is read by the <var>Ti</var> thread.
+ * This thread should not block for a long period of time on anything but the
+ * key driver.
+ * <dt> Lw <dd> Called with the main window manager lock held. Because the
+ * window manager is a very low-level system service, there are few other
+ * system services you can call with this lock held. It is explicitly okay to
+ * make calls into the package manager and power manager; it is explicitly not
+ * okay to make calls into the activity manager. Note that
+ * {@link android.content.Context#checkPermission(String, int, int)} and
+ * variations require calling into the activity manager.
+ * <dt> Li <dd> Called with the input thread lock held. This lock can be
+ * acquired by the window manager while it holds the window lock, so this is
+ * even more restrictive than <var>Lw</var>.
+ * </dl>
