//Purpose: Provide a professional looking header area for dialog controls 
//       : that will display an icon, a title phrase in bold, and a 
//       : description phrase. And also provide a custom background color 
//       : and custom header height. 
//		   
//Note   : This code was insipired by Mustafa Demirhan's article about hacking 
//		 : the CPropterySheet. See link below.
