	The Xlib Reference Manual (O'Reilly Assoctiates books) says
that setting cursor = NONE in a call to XDefineCursor will cause
no cursor to be displayed. The sample server causes the parent
window cursor to be displayed, as if XUdefineCursor was called.
The sample server Xlib implementation of XDefineCursor uses a
ChangeWindowAttributes protocol request to set the cursor. The X
protocol spec (R2) says "Changing the cursor of a root window to None
restores the defalut cursor". The Xlib implementations seems to
contradict the Xlib Reference Manual and the Protocol spec just is
unclear.
