IVtkTools_ShapePicker does not define GetPickPosition() point, only picked entity.
So yes, it might be considered as bug or implementation limitation.

e.g. one picking many objects. how to get top one? seems only be determined by pick position

The list of results is ordered from topmost to farthest.
