x11: Relax requirements for setting ParentRelative

Browse Source 
XSetWindowBackgroundPixmap() will throw BadMatch only in the case of a
different parent window depth. Different visuals are fine and actually
expected in Gtk+ 3.16 (since we don't stick to the system default visual
but try to pick a better one).
