+/**
+ * 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.
