// 
// CFPSPropertyListItem
// Created by Matt Gullett
// (c) 1998
//
// This class is a support class for the CFPSPropertyList custom
// control.  This class implements the property item objects which
// get drawn on demand.  Several property types are supported.
// these are :
//           TEXT
//           INTEGER
//           LONG
//           FONT
//           COLOR
//           FILE
//           COMBO BOX
//           BOOLEAN
// 
// DEPENDENCIES : CFPSPropertyList class
//
// NOTE :
// This class is not usually accesed directy as wrapper functions
// are implemented in the CFPSPropertyList class for creating
// and setting up these items.  The PROPERTYITEMSETUP structure
// is provided to permit setting up the configuration of these
// objects.  In order to keep windows resource usage low, no
// GDI objects are maintained for object duraction, instead they
// are created on demand
