* This protocol is used to send input events from the UI process to the
* GPU process for handling by APZ. There is one instance per top-level
* compositor, or in other words, one instance per concrete APZCTreeManager
* instance. The child side lives on the controller thread in the UI process,
* ie the main thread on most platforms, but the Android UI thread on Android.
* The parent side lives on the main thread in the GPU process. If there is no
* GPU process, then this protocol is not instantiated.
