Redesign of selection mechanism: - implemented 3-level BVH tree for selection; - selection now calculates in 3D space; - intersection tests were moved to SelectMgr_BaseFrustum descendants; - removed .cdl files in Select3D and .cdl related to selection in MeshVS; - SelectMgr_ViewerSelectors are now shared between local and global contexts; - transformations of sensitive entities are now stored in SelectMgr_SelectableObject only. Sensitive entities are independent from transformations, it is applied to SelectMgr_SelectingVolumeManager instance only; - connected and multiple connected interactive objects are now represented by their child objects only for SelectMgr_SelectionManager; - if interactive object has child objects, they will be stored as separate objects in SelectMgr_SelectionManager now. - test cases bugs/vis/bug24623_1, bug24623_2, bug24623_3, bug24623_4 to test performance and memory issues.
