// dispenser.h
// Project: Nostril (aka Postal)
//
//	History:
//		03/19/97	JMI	Started this dispenser item class using CItem3d as a 
//							template.
//
//		03/20/97	JMI	Added m_ulFileVersion, InstantiateDispensee(), and
//							SaveDispensee() members.  Removed m_idDispensee.
//
//		03/21/97	JMI	Added ms_sDispenseeFileCount.
//
//		04/23/97	JMI	Added new logic type Exists and added a max for the number
//							of dispensees and a current number of dispensees dispensed.
//
//		06/14/97	JMI	Made default logic type Timed.
//
//		06/27/97	JMI	Added m_imRender and m_bEditMode.
//
//		06/28/97	JMI	Added a function to render the dispensee, 
//							RenderDisipensee().
//
//		06/30/97	JMI	m_sDispenseeHotSpotX, m_sDispenseeHotSpotY, and 
//							m_rcDispensee.
//
//		07/10/97	JMI	Added GetClosestDude().
//							Also, added new logic type DistanceToDude.
//
//		07/21/97	JMI	Added GetX(), GetY(), and GetZ().	
//
//		07/28/97	JMI	Changed m_lLogicParm1,2,3 to m_alLogicParms[4] (adding one
//							logic parm while changing the storage technique).
