0030058: Visualization, Select3D_SensitivePrimitiveArray - the selection is not fast enough

Browse Source 
Select3D_SensitiveSet::Matches() has been improved to check if BVH node is fully included by selection volume
and pass this information to overlapsElement()/elementIsInside() interfaces
to avoid expensive partial overlapping checks for individual elements.
Select3D_SensitivePrimitiveArray implements this new interface to improve partial overlapping performance.
Select3D_SensitivePrimitiveArray::Matches() now handles rectangle selection for sub-elements when Elements map is defined.
Added missing const to SelectMgr_BaseFrustum::Overlaps() methods.

AIS_PointCloud has been extended with new selection mode for collecting selected nodes

Draw Harness command vdrawparray has been extended with an option -shape
allowing to create a triangulation from tessellated shape.
