-//The procedures of monitoring when the scene finishes loading visually,
-//i.e., no pixel differences among frames, are:
-//1, freeze all dynamic objects and avatars;
-//2, (?) disable all sky and water;
-//3, capture frames periodically, by calling "capture()";
-//4, compute pixel differences between two latest captured frames, by calling "compare()", results are stored at mDiff;
-//5, compute the number of pixels in mDiff above some tolerance threshold in GPU, by calling "calcDiffAggregate()";
-//6, use gl occlusion query to fetch the result from GPU, by calling "fetchQueryResult()";
-//END.
