 *	class		:	CKCSideBannerWnd
 *	author		:	Peter Mares / kinkycode.com ([e-mail])
 *	base class	:	CWnd (MFC)
 *	notes		:	A control to act as a banner to a window. More of a look'n'feel
 *					control.
 *					NOTE: Remember to link to MSIMG32.LIB to enable GradientFill()
 *
 *	Blurb		:	Its free, it feels good and its from South Africa :)
 ****************************************************************************
 *	Version History:
 *
 *	v0.1 (20-Oct-2003)
 *
 *	- First public release
 *
 *	v0.2 (24-Oct-2003)
 *
 *	- Added (Set)(Get)ColTxtTitle() and (Set)(Get)ColTxtCaption() functions
 *	- Revised all other updates since initial release
 *
 *	v0.3 (25-Oct-2003)
 *
 *	- Changed the SetIcon() function to support a delete flag
 *	- Added SetTexture() function
 *	- Fixed a resource leak
 *
 *	v0.31 (26-Oct-2003)
 *
 *	- Added UNICODE support to the control - thanks to Abraxas23
 *
 *	v0.32 (29-Oct-2003)
 *
 *	- Added support for gradient drawing without the dependancy on MSIMG32.LIB
 *    Used John A. Johnson's GradientFill() function, and used dynamic linking
 *	  of the MSIMG32.DLL (thanks to Irek Zielinski's code)
