-// The BlimpInputHandlerWrapper isolates all input handling processing done on |

-// from the BlimpInputManager and sends them to the ui::InputHandlerProxy. |
-// The class is created on the main thread, but becomes bound to the compositor |
-// thread when it binds to the ui::InputHandlerProxy, and should only be called |
-// on the compositor thread. |
-// The creater of this class ensures that the cc::InputHandler is destroyed |
-// before this class is destroyed. This is necessary to ensure that the |
-// compositor thread components of this class, i.e., the ui::InputHandlerProxy |
-// and any weak ptrs dispensed for posting tasks to the class on the compositor |
-// thread, are destroyed before the class is destroyed on the main thread. |
