// AUTHOR:  James White (feel free to remove or otherwise mangle any part) 
// 
// DESCRIPTION: This class is alarmingly similar to the CColourPicker control 
//	created by Chris Maunder of www.codeproject.com. It is so as it was blatantly 
//	copied from that class and is entirely dependant on his other great work 
//  in CColourPopup. I was hoping for (cough.. gag..) a more Microsoft look 
//  and I think this is pretty close. Hope you like it.
