0026195: Visualization - optimize selection algorithms

Browse Source 
- initial transformation of triangulation is now applied to selecting frustum;
- switched from NCollection_Vec3 to gp collections to avoid conversions and usage of macros;
- calculation of frustum was refactored to reduce its build time;
- double pixel tolerances for selection were replaced by integer ones;
- switched to splitting along the main axis only in SelectMgr BVH selection primitive sets.
