// 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.
