/**

* The PCompositorManager protocol is the top-level protocol between the

* compositor thread and the creators of compositors. It exists in the
|
|
* following conditions:
|
|
* - One PCompositorManager between the GPU process and each content process.
|
|
* If the GPU/UI processes are combined, there is one PCompositorManager
|
|
* between the combined GPU/UI process and each content process.
|
|
* - One PCompositorManager between the GPU process and the UI process. If
|
|
* they are combined, there is still one PCompositorManager, but both the
|
|
* child and parent live in the same process.
|
|
* The intention for this protocol is to facilitate communication with the
|
|
* compositor thread for compositor data that is only shared once, rather than
|
|
* per PCompositorBridge instance.
