665 -- 1. TRUE. Drawing immediate mode structures directly to the front buffer over the scene image.
666 -- Fast, so preferred for interactive work (used by default).
667 -- However these extra drawings will be missed in image dump since it is performed from back buffer.
668 -- Notice that since no pre-buffering used the V-Sync will be ignored and rendering could be seen
669 -- in run-time (in case of slow hardware) and/or tearing may appear.
670 -- So this is strongly recommended to draw only simple (fast) structures.
671 -- 2. FALSE. Drawing immediate mode structures to the back buffer.
672 -- The complete scene is redrawn first, so this mode is slower if scene contains complex data and/or V-Sync is turned on.
673 -- But it works in any case and is especially useful for view dump because the dump image is read from the back buffer.
