commit bfeeae6adf9b2a7b375dd4cf917be0123c6ccefa
Author: Mike Blumenkrantz <zm...@osg.samsung.com>
Date:   Fri Sep 25 18:31:30 2015 -0400

    fix handling of x11 ICCCM WithdrawnState
    
    according to ICCCM 4.1.4:
    Only the client can effect a transition into or out of the Withdrawn state
    
    withdrawn windows cannot be shown under any circumstances. the best that can
    be done is to try mapping the window and hope it decides to appear.
    
    to prevent any inadvertent showing of the window before it leaves the
    withdrawn state, we play games with the E_Client->ignored flag in order
    to skip client evals until we get notified that maybe we want to stop
    skipping those evals
    
    ref T2745
