// DESCRIPTION                                                             
//
//		This tooltip control implements:
//
//		o An immediate popup tip window
//		o Normal control tooltips
//
//		The tip window can display an icon and multi-line
//		tip text.  Seperate multiple text lines with a '\n'.
//		The tip window's colors are derrived from
//		system window, window text, and scroll bar colors.
//
//		Create the control by calling the Create() method.
//
//		To display immediate tips, call the Show() method.
//		Call SetIcon() to set the icon used for immediate tips.
//
//		Use AddTool() to add tool windows.  RelayEvent() must
//		be called from the parent windows's PreTranslateMessage().
//
//		Call SetShowDelay() to adjust the tip popup delay.
//
//		Call SetFont() to change the tooltip text font.  The default
//		is the system default GUI font.
