### Window placement algorithms, choose one of these and ebind it to the ###
### ob.EventAction.PlaceWindow event.                                    ###
###                                                                      ###
### Also see historyplacement.py for the history placement module which  ###
### provides an algorithm that can be used in place of, or alongside,    ###
### these.                                                               ###
