* PAPZCTreeManager is a protocol for remoting an IAPZCTreeManager. PAPZCTreeManager
* lives on the PCompositorBridge protocol which either connects to the compositor
* thread in the main process, or to the compositor thread in the gpu processs.
* PAPZCTreeManagerParent lives in the compositor thread, while PAPZCTreeManagerChild
* lives in the main thread of the main or the content process. APZCTreeManagerParent
* and APZCTreeManagerChild implement this protocol.
