-// This is the phase offset in nanoseconds of the software vsync event
-// relative to the vsync event reported by HWComposer. The software vsync
-// event is when SurfaceFlinger and Choreographer-based applications run each
-// frame.
-//
-// 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
-// conservatively (or at least with awareness of the trade-off being made).
