 The Select widget currently performs deep selection even when the user
 clicks on a single point (as opposed to dragging a rectangle). Users have
 requested that a single click only return the topmost feature, as is
 common in other applications.

 A new parameter, !PointClickSingleSelect, will be added to the Select
 widget to allow the behaviour to be controlled. If set to true, only the
 topmost feature will be selected. If set to false, any features below the
 clicked point will be selected, up to the value of the !MaxFeatures
 setting.
