_NET_WM_WINDOW_TYPE_DESKTOP. This makes the desktop focusable and greatly

simplifies implementation of the file manager. It is also faster than

managing lots of small shaped windows. The file manager draws the background

on this window. There should be a root property with a window handle for use

in applications that want to draw the background (xearth).
