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.
1) Add SelectMgr_EntityOwner::IsSelected() and SelectMgr_EntityOwner::SetSelected() methods to determine if corresponding entity is selected.
They replace functionality of SelectMgr_EntityOwner::State() methods that are deprecated now.
2) AIS_InteractiveContext::ToHilightSelected() and AIS_InteractiveContext::SetToHilightSelected() is to be used to enable highlighting of selected objects.
3) By default selected objects are highlighted (new behavior)
4) Add ViewerTest_ViewerCommands: vhighlightselected command to enable/disable 'highlight selected objects' mode.
5) AIS_LocalContext, AIS_InteractiveContext : style changes in Select and ShiftSelect methods.
6) Add test cases /bugs/vis bug23649_1 and /bugs/vis bug23649_2 to test highlighting of selected objects in local context.
7) Add test cases /bugs/vis bug23649_3 and /bugs/vis bug23649_4 to test highlighting of selected objects in neutral point.
