////////////////////////////////////////////////////////////////////////////////////////////
//	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.
