| APZInputBridge.h | Represents the outcome of APZ receiving and processing an input event.
 This is returned from APZInputBridge::ReceiveInputEvent() and related APIs. | 13235 | 
        
          | APZPublicUtils.h | 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
 initialized earlier. | 3577 | 
        
          | APZSampler.h | 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. | 5209 | 
        
          | APZUpdater.h | 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. | 10312 | 
        
          | CompositorController.h | Ask the compositor to schedule a new composite. | 970 | 
        
          | CompositorScrollUpdate.h | An update sent by APZ to interesting consumers (e.g. GeckoView)
 to inform them, on every composite, about the effective visual
 scroll offset and zoom level of the root content APZC at
 composition time. | 1939 | 
        
          | GeckoContentController.h | 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
 corresponding transform. | 8047 | 
        
          | GeckoContentControllerTypes.h | APZ started modifying the view (including panning, zooming, and fling). | 2076 | 
        
          | IAPZCTreeManager.h | Set the keyboard shortcuts to use for translating keyboard events. | 5797 | 
        
          | MatrixMessage.h |  | 2360 |
