* PAPZ is a protocol for remoting a GeckoContentController. PAPZ 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.
*
* PAPZParent lives in the compositor thread, while PAPZChild lives wherever the remoted
* GeckoContentController lives (generally the main thread of the main or content process).
* RemoteContentController implements PAPZParent, while APZChild implements PAPZChild.
*
* PAPZ is always used for ContentProcessController and only used for ChromeProcessController
* when there is a gpu process, otherwhise ChromeProcessController is used directly on the
* compositor thread. Only the methods that are used by the [Chrome,Content]ProcessController
* are implemented. If a new method is needed then PAPZ, APZChild, and RemoteContentController
* must be updated to handle it.
