||Represents the outcome of APZ receiving and processing an input event.
This is returned from APZInputBridge::ReceiveInputEvent() and related APIs.
||Initializes the global state used in AsyncPanZoomController.
This is normally called when it is first needed in the constructor
of APZCTreeManager, but can be called manually to force it to be
||This interface exposes APZ methods related to "sampling" (i.e. reading the
async transforms produced by APZ). These methods should all be called on
the sampler thread.
||This interface is used to send updates or otherwise mutate APZ internal
state. These functions is usually called from the compositor thread in
response to IPC messages. The method implementations internally redispatch
themselves to the updater thread in the case where the compositor thread
is not the updater thread.
||Ask the compositor to schedule a new composite.
||Notifies the content side of the most recently computed transforms for
each layers subtree to the root. The nsTArray will contain one
MatrixMessage for each layers id in the current APZ tree, along with the

||Set the keyboard shortcuts to use for translating keyboard events.
