+# - The phase offset between hardware vsync and when apps are woken up by the
+#   Choreographer callback
+# - The phase offset between hardware vsync and when SurfaceFlinger wakes up

+# Their values may be tuned to trade off between display pipeline latency (both
+# overall latency and the lengths of the app --> SF and SF --> display phases)
+# and frame delivery jitter (which typically manifests as "jank" or "jerkiness"

+# relatively low amount of jitter at the expense of roughly two frames of
+# app --> display latency, and unless significant testing is performed to avoid
+# increased display jitter (both manual investigation using systrace [1] and
+# automated testing using dumpsys gfxinfo [2] are recommended), they should not
