       XPropertyEvent - PropertyNotify event structure

       The structure for events contains:

       typedef struct {
	 int type;		/* PropertyNotify */
	 unsigned long serial;	/* # of last request processed by
				     server */
	 Bool send_event;	/* true if came from a SendEvent
				     request */
	 Display *display;	/* Display the event was read from */
	 Window window;
	 Atom atom;
	 Time time;
	 int state;		/* PropertyNewValue or
				     PropertyDeleted */
       } XPropertyEvent;

       When you receive this event, the structure members are set as follows.

       The type member is set to the event type constant name that uniquely identifies it.  For example, when the X server reports a event to a
       client application, it sends an structure with the type member set to The display member is set to a pointer to the display the event was
       read on.  The send_event member is set to if the event came from a protocol request.  The serial member is set from the serial number
       reported in the protocol but expanded from the 16-bit least-significant bits to a full 32-bit value.  The window member is set to the win-
       dow that is most useful to toolkit dispatchers.

       The window member is set to the window whose associated property was changed.  The atom member is set to the property's atom and indicates
       which property was changed or desired.  The time member is set to the server time when the property was changed.  The state member is set
       to indicate whether the property was changed to a new value or deleted and can be or The state member is set to when a property of the win-
       dow is changed using or (even when adding zero-length data using and when replacing all or part of a property with identical data using or
       The state member is set to when a property of the window is deleted using or, if the delete argument is
