* XrMenu(menuInstance, message, data)
*

* INT32 message;
* INT8 * data;
*
* Description:
* -----------
* This is the menu manager. It provides a pop-up, cascading
* menuing system for the X-ray toolbox. The most important
* message for the programmer are MSG_NEW and MSG_ACTIVATEMENU.
* MSG_NEW creates the menu, MSG_ACTIVATEMENU associates it
* with a registered X-ray window. Output form the menu
* manager is returned transparently to the program by the
* XrInput() module. The programmer will not normally call
* the menu manager for input directly.
*
* The other messages support the modification and query of
* the menu structure including sub-menu support. For a complete
* description of the menu manager, refer to the X-ray toolbox
* manual.
*
*
* Inputs:
* ------
* menuInstance = This value indicates to the menu manager,
* which menu should be dealt with.
*
* message = Contains the command to be executed.
*
* data = Varies depending on the message, But is generally
* a pointer to a structure.
*
*
* Outputs:
* -------
* menuInstance = Returned from MSG_NEW.
*
* TRUE = Returned upon successful completion of a message.
*
* NULL = Returned if something went wrong.
*
* xrError = The error variable is set to one of several values
* upon failure of this routine.
