+//
+// This phase offset allows adjustment of the minimum latency from application
+// wake-up (by Choregographer) time to the time at which the resulting window
+// image is displayed. This value may be either positive (after the HW vsync)
+// or negative (before the HW vsync). Setting it to 0 will result in a
+// minimum latency of two vsync periods because the app and SurfaceFlinger
+// will run just after the HW vsync. Setting it to a positive number will
+// result in the minimum latency being:
+//
+// (2 * VSYNC_PERIOD - (vsyncPhaseOffsetNs % VSYNC_PERIOD))
+//
+// Note that reducing this latency makes it more likely for the applications
+// to not have their window content image ready in time. When this happens
+// the latency will end up being an additional vsync period, and animations
+// will hiccup. Therefore, this latency should be tuned somewhat
