+ * Choreographer coordinates the timing of frame rendering. This is the C version of the
+ * android.view.Choreographer object in Java.
+ *
+ * As of API level 33, apps can follow proper frame pacing and even choose a future frame to render.
+ * The API is used as follows:
+ * 1. The app posts an {@link AChoreographer_vsyncCallback} to Choreographer to run on the next
+ * frame.
+ * 2. The callback is called when it is the time to start the frame with an {@link
+ * AChoreographerFrameCallbackData} payload: information about multiple possible frame
+ * timelines.
+ * 3. Apps can choose a frame timeline from the {@link
+ * AChoreographerFrameCallbackData} payload, depending on the frame deadline they can meet when
+ * rendering the frame and their desired presentation time, and subsequently
+ * {@link ASurfaceTransaction_setFrameTimeline notify SurfaceFlinger}
+ * of the choice. Alternatively, for apps that do not choose a frame timeline, their frame would be
+ * presented at the earliest possible timeline.
+ *   - The preferred frame timeline is the default frame
+ * timeline that the platform scheduled for the app, based on device configuration.
+ * 4. SurfaceFlinger attempts to follow the chosen frame timeline, by not applying transactions or
+ * latching buffers before the desired presentation time.
