New overload for method OSD::SetSignal() is added accepting argument specifying how to set or unset handlers.
New enum OSD_SignalMode describes different modes of signal handlers setting used in extended version of OSD::SetSignal().
Method OSD::SignalMode() returns mode set by the last call to SetSignal().
Method OSD::IsFloatingSignalSet() is changed to return value based on actual floating point exception flags (rather than on variable set by previous call to SetSignal()).

Added new method OSD::SetThreadLocalSignal() intended to setup thread-specific handlers (e.g. _set_se_translator() on Windows) and FPE settings.
OSD_ThreadPool and Media_PlayerContext now use new method instead of OSD::SetSignal(), to avoid overriding global handlers.

dsetsignal syntax has been extended to support choice of signal handling mode.

Clipping range has been moved from SelectMgr_RectangularFrustum to SelectMgr_SelectingVolumeManager

This fixes an issue when Clipping is customized per-object within SelectMgr_ViewerSelector::traverseObject()

displaying orientation of the main axes of the model space in the viewer.
Each side, edge, or corner of the cube corresponds to particular orientation of the camera,
and the class provides methods to move the camera to corresponding position (with animation if needed).

AIS_InteractiveContext::LastActiveView(), added new property returning the last View processed by MoveTo() event.
AIS_InteractiveContext::BoundingBoxOfSelection(), added method returning bounding box of selected objects.
SelectMgr_EntityOwner::HandleMouseClick(), added new callback for handling
mouse clicks by owner itself without automatic highlighting and clearing previous selection.

The behavior of V3d_Viewer::AddZLayer() has been adjusted to append
