514 -- Notice that since no pre-buffering used the V-Sync will be ignored and rendering could be seen
515 -- in run-time (in case of slow hardware) and/or tearing may appear.
516 -- So this is strongly recommended to draw only simple (fast) structures.
517 -- 2. FALSE. Drawing immediate mode structures to the back buffer.
518 -- The complete scene is redrawn first, so this mode is slower if scene contains complex data and/or V-Sync is turned on.
519 -- But it works in any case and is especially useful for view dump because the dump image is read from the back buffer.
