57 * Check the GL Sync objects. This is called from Render Thread.
58 * If the GlSyncObject has been triggered, then atomically set the sync trigger
60 void PollSyncObject();
63 * Check the sync trigger. This is called from Update Thread, so atomically reads the sync trigger
64 * It clears the sync trigger if it was set.
65 * @return true if the tracker has been synced
70 * Atomically reset the sync trigger. This may be called from any thread
75 * Atomically sets the sync trigger. This may be called from any thread
