This is true. The recommended usage is to reparent a window of your own
creation (and your own visual) to be a child of the overlay window.
I just assigned the default visual to the overlay window because you
need to use some visual when creating a window in the server. The
overlay window is typically not rendered to directly. It's more of a
container.
