//////////////////////////////////////////////////////////////////////////////////////////// 
//	CMenuXP is a class derived from CMenu, using ownerdraw technology. 
//	I named it MenuXP because I once expected it to be like the menus 
//	in OfficeXP and WindowsXP, but I failed to accomplish it. The big 
//	difficulty is I cannot convert the 3D border of the menu into flat. 
//	So I giveup. And I hope it still usefull to you. 
//	 
//	I construt the class from scribble, but some of the drawing code is copy from the class 
//	CCoolMenuManager. I also use a class named CBCGKeyHelper from BCGControlBar to show 
//	accelerator key text. 
// 
//	Usage: 
//	Seee Example 
// 
//	Features: 
//	1. Menu with icons, like in office 97 
//	2. A sidebar in any level of the popup menu 
//	3. Support button style menuitem, it appear in some drawing toolbars of office suite 
//	4. All colors and font and size can be customized 
// 
//	Use it as you like. bug report and improvement is welcome.
