- * VisualizationScheduler is singleton class that schedules
- * visualization redraws. 
- * 
- * Scheduler has three behaviour patters: 
- * 
- * ONCE : Redraws all visualizations one by one and then sleeps for
- *        a while so that visualizations won't use all available cpu-time.
- *    
- * ALWAYS : Redraws one visualization and sleeps before updating next
- *          visualization.
- *    
- * OFF : uses asyncExec busy-loop (doesn't block eclipse, but other applications may suffer)
