SubIntensityOn, SubIntensityOff, FitSelected, EraseGlobal, ClearGlobal, ClearGlobalPrs.
In addition, the API for immediate viewer update has been removed from V3d_View and Graphic3d_StructureManager classes
(enumerations *Aspect_TypeOfUpdate* and *V3d_TypeOfUpdate*):
V3d::SetUpdateMode(), V3d::UpdateMode(), Graphic3d_StructureManager::SetUpdateMode(), Graphic3d_StructureManager::UpdateMode().
The argument theUpdateMode has been removed from methods Graphic3d_CView::Display(), ::Erase(), ::Update().
Method Graphic3d_CView::Update() does not redraw the view and does not re-compute structures anymore.
