Fix a crash in gnome-terminal when using a compositor

Browse Source 
In this case, gnome-terminal sets an RGBA visual on its window,
and we need to be careful when creating the icon pixmap, to create
the pixmap with the same depth as the visual, or we risk a BadMatch
from XRenderCreatePicture deep inside cairo.
