DESCRIPTION
 If a cursor is set, it will be used when the pointer is in the window. If the cursor is  
None, it is equivalent to  
XUndefineCursor.
XDefineCursor can generate  BadCursor and  BadWindow errors.
The  XUndefineCursor function undoes the effect of a previous  XDefineCursor for this window. When the pointer is in the window, the parent's cursor will now be used. On the root window, the default cursor is restored.
XUndefineCursor can generate a  BadWindow error.
