-// The BlimpInputManager handles input events for a specific web widget. The
-// class processes ui::events to generate web input events which are forwarded
-// to the compositor to be handled on the compositor thread. If the event can
-// not be handled locally by the compositor, it is given to the
-// BlimpInputManagerClient to be sent to the engine.
-//
-// The BlimpInputManager is created and destroyed on the main thread but can be
-// called from the main or compositor thread. It is safe for the
-// BlimpInputManager to be called on the compositor thread because:
-// 1) The only compositor threaded callers of the BlimpInputManager are the
-// BlimpInputManager itself.
-// 2) BlimpInputManager blocks the main thread in its dtor to ensure that all
-// tasks queued to call it on the compositor thread have been run before it is
-// destroyed on the main thread.
-//
-// It is *important* to destroy the cc::InputHandler on the compositor thread
-// before destroying the BlimpInputManager.
