Original issue's description:
> Read compositor VSync information from platform, when possible
> 
> The current query of VSync information through the GL context can be unreliable
> on platforms that can dynamically disable vblanks, or multi-monitor setups.
> Preferentially query the VSync information through the platform windowing
> system (presently: XRandR on CrOS) when possible.
> 
> BUG=328953
> TEST=local build, run on CrOS snow
