$OpenBSD: patch-src_Window_cc,v 1.7 2012/08/27 10:45:44 dcoppa Exp $

When a screen has more heads and some part of the screen is not on
any head and some window is placed into this invisible area then
the window is invisible which sucks. This patch repositions such
windows so that they are visible.
