Extended SelectBasics_PickResult structure by myObjPickedPnt field, which contained the value of the 3d point on the selected object. Changed all Overlaps methods. Parameter theDepth replaced on object of the structure SelectBasics_PickResult. This approach will be able to add new fields to SelectBasics_PickResult structure without big changes in modules which contained Overlaps method.
