// ==========================================================================   
// HISTORY:	   
// ==========================================================================   
//		1.01	13 Aug 1998 - Andrew Bancroft [ABancroft@lgc.com] - Since we've already  
//							  added the entire toolbar to the imagelist we need to  
//							  increment nNextImage even if we didn't add this button to  
//							  m_mapIDtoImage in the LoadToolbar() method. 
//		1.01a	13 Aug 1998	- Peter Tewkesbury - Added AddSingleBitmap(...) 
//							  method for adding a single bitmap to a pulldown 
//							  menu item. 
//		1.02	13 Aug 1998 - Omar L Francisco - Fixed bug with lpds->CtlType 
//							  and lpds->itemData item checking. 
//		1.03	12 Nov 1998	- Fixes debug assert in system menu. - Wang Jun 
//		1.04	17 Nov 1998 - Fixes debug assert when you maximize a view - Wang Jun 
//							  window, then try to use the system menu for the view. 
//		1.05	09 Jan 1998 - Seain B. Conover [sc@tarasoft.com] - Fix for virtual  
//							  key names. 
//		1.06	24 Feb 1999 - Michael Lange [michael.home@topdogg.com] - Fix for memory  
//							  leak in CMyItemData structure, added a destructor that  
//							  calls text.Empty(). 
//							- Boris Kartamishev [kbv@omegasoftware.com] - Fix for resource 
//							  ID bug. 
//							- Jeremy Horgan [jeremyhorgan@hotmail.com] - During  
//							  accelerator key processing OnInitMenuPopup() calls  
//							  ConvertMenu() which allocates a new CMyItemData for each  
//						      menu item. This is memory is normally freed by a call to  
//						      OnMenuSelect(), which is not called when processing  
//							  accelerator keys. This results in a memory leak. This was 
//							  fixed by modifying the ~CCoolMenuManager() destructor. 
//		1.07	24 Feb 1999 - Koji MATSUNAMI [kmatsu@inse.co.jp] - Fixed problem with  
//							  popup menus being drawn correctly as cool menus.
