- Added new chrome-only webidl methods to be used by browser UI and WebExtensions - Implemented bitmasked group visibility for VR sessions to enable switching between chrome and regular content presentations. - Implemented throttling mechanism to avoid runaway, unthrottled render loops for VR sessions that are hidden by group visibility bitmasks or due to lower level platform VR events, such as during the Oculus "Health and Safety Warning". - Simplified the PVRManager IPC protocol while extending it to support VR session groups and later WebVR content performance profiling API's. - Removed the last WebVR related sync IPC call.
