 * Figure_xxx_rect establishes a new rect for one tool, without
 *	requiring the tool's windowfd;  this implies the window should
 *	not yet be in the display tree when these routines are called.
 * Acquire_xxx_rect does the same job, but takes care of removing / 
 *	reinserting the window in the display tree.
 * Inquire_xxx_rect returns the same information Aquire would,
 *	without advancing the global positioning information.
 * Set_xxx_rect handle the rect changes for operations Front / Back
 *	and Full / Open / Close
