Summary0033209: No possibility to select only objects visible to user using API of AIS_InteractiveContext
DescriptionIn contrast to SelectDetected() neither SelectPoint(), nor SelectPolygon(), nor SelectRectangle() allow to select objects that are visible to user only, i.e. having two objects one of which is behind another, both will be selected using these methods despite of the first one is visually hidden and may be omitted. In other words current selection scheme allows to select objects by X-Ray so it passes through the entire scene, however in some scenarios it is preferable to stop at the first hit on the closest object.

Changing PickingStrategy parameter seems to have no effect.
