-    // When we use an input method (or an input method editor), we receive
-    // two events for a keypress. The former event is a keydown, which
-    // provides a keycode, and the latter is a textinput, which provides
-    // a character processed by an input method. (The mapping from a
-    // keycode to a character code is not trivial for non-English
-    // keyboards.)
-    // To support input methods, Safari sends keydown events to WebKit for
-    // filtering. WebKit sends filtered keydown events back to Safari,
-    // which sends them to input methods.
-    // Unfortunately, it is hard to apply this design to Chrome because of
-    // our multiprocess architecture. An input method is running in a
-    // browser process. On the other hand, WebKit is running in a renderer
-    // process. So, this design results in increasing IPC messages.
-    // To support input methods without increasing IPC messages, Chrome
-    // handles keyboard events in a browser process and send asynchronous
-    // input events (to be translated to DOM events) to a renderer
-    // process.
-    // This design is mostly the same as the one of Windows and Mac Carbon.
-    // So, for what it's worth, our Linux and Mac front-ends emulate our
-    // Windows front-end. To emulate our Windows front-end, we can share
-    // our back-end code among Windows, Linux, and Mac.
