0027538: Visualization, AIS_InteractiveContext::Display() - do not erase previous display mode.
AIS_InteractiveContext::Display() does not erases old presentation modes of interactive object anymore giving us performance benefit AIS_InteractiveContext::Display() is used. Instead, the method marks them hidden in the same way as AIS_InteractiveContext::SetDisplayMode() and ::UnsetDisplayMode().
