- 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.
