No, the depth need not be the same as that of the parent, but it does
have to be one supported by the visual you're using.  Notice that the
10th argument to XCreateWindow is the visual.  You can use
XMatchVisualInfo() to find a visual with the depth you want.  Your
server/hardware may not support any visuals with depths other than 4.
